Magnets have two poles, north and south, that exert an invisible magnetic force. Magnets either attract or repel each other depending on whether the poles that face each other are opposite or the same. If a magnet's north pole faces another's south pole, they attract, but if two same poles face each other, such as north to north, they repel each other due to the magnetic force pushing against each other. A paperclip can be identified as having a north or south pole based on whether it is attracted or repelled by the poles of a reference magnet.

Magnets
Magnets can attract objects made of iron, steel, or nickel without touching them by pulling the objects through solid, liquid, or gas. Magnets have two poles, a North and a South, that either attract or repel each other or other magnets depending on whether the poles are the same or different. Strong magnets can attract objects from farther away than weaker magnets.
Magnets
Magnets can be natural or artificial. Natural magnets occur in nature and have a weak magnetic field, while artificial magnets are man-made and have a stronger field. Magnets have two poles, north and south, where attraction is strongest. Unlike poles attract and like poles repel. Magnets can be used for many purposes, such as in speakers, motors, generators, and compasses. They work by aligning the magnetic domains in metals and can be made by stroking or using electricity to orient the domains.
Magnetism
Magnetism is a force that can attract or repel magnetic materials like iron. It is a property of substances that are attracted to magnets. There are different types of magnetism including permanent magnetism, temporary magnetism caused by magnetic fields, and electromagnetism related to electric currents and changing magnetic fields. Magnets have north and south poles and attract unlike poles while repelling like poles. The strength of magnetic force depends on the strength of the magnets and the distance between them.
Magnetism
The document discusses several laws and concepts related to magnetism. It states that like poles of magnets repel each other, while unlike poles attract. A compass arrow points to magnetic north. Induced magnetism explains how magnetic materials can become magnetized when placed near a magnet due to magnetic induction. A magnetic field is the region around a magnet where its magnetic effects can be detected, with field lines running from the north to south pole. Permanent magnets made of steel retain their magnetism while temporary magnets made of iron lose theirs over time.
MAGNETS AND MAGNETIC MATERIALS
An introductory approach to teaching the very basics and foundation of MAGNETS AND MAGNETISM. Very useful for basic elementary lessons.
Magnets
Magnets are materials or objects that produce magnetic fields and attract ferromagnetic materials like iron. Permanent magnets are made from "hard" ferromagnetic materials that maintain their own magnetic fields. Common uses of magnets include speakers, medical imaging devices, compasses, magnetic storage media, and toys. There are several types of permanent magnets including neodymium iron boron, samarium cobalt, alnico, and ferrite magnets.

Magnetism
Magnetism is the force of attraction or repulsion between two substances. Ancient sailors used magnetite, the first known magnetic rock, as a compass by tying a piece to a string and suspending it to determine directions. Atoms have magnetic properties due to their spinning electrons and electric charge, but in most objects the magnetic domains of atoms are not uniformly aligned, resulting in weak magnetic forces. Strong magnetism can be induced by exposing objects to magnetic fields, which causes atomic domains to align uniformly. The first natural magnets were formed when iron-containing volcanic magma was magnetized by contact with the Earth's magnetic field.

Magnetism
This document provides an overview of magnetism and magnetic fields. It discusses that magnetism is caused by the motion of charged particles and the strongest force is at the poles. Magnetic fields are represented by lines and form closed loops. Permanent magnets are often made of steel and electrons align to produce magnetic fields. Magnets can lose magnetism through heating, striking, or placing similar poles together. Larger magnets are not necessarily stronger. Maglev trains use magnetic fields for lift, propulsion and guidance.
Maglev Complete Presentation
Magnetism and magnetic levitation trains are discussed. There is some discussion of implementing maglev trains in parts of the US. Three methods of magnetic levitation are described: 1) Using magnets on the track and train results in repulsion and levitation but unstable equilibrium. 2) AC levitation uses an AC electromagnet on the train and metal tracks but energy decays quickly. 3) Dynamic levitation uses a magnet on the train and metal tracks, producing the least energy dissipation by allowing the train to move fast enough initially.
Magnetism
Magnetism allows certain objects called magnets to exert forces on each other without touching. A magnetic field is a region of space where a magnet will experience a non-contact force. Magnets have two poles, a north and south pole, where like poles repel and opposite poles attract. The Earth also has a magnetic field that protects us from charged particles from the sun and allows compasses to work by pointing to magnetic north.
Magnetism
Magnets have been known and used for navigation for centuries, with the ancient Greeks using a magnetic stone called magnetite. Magnetism is the force of attraction or repulsion between magnetic materials due to the arrangement of electrons in their atoms. The Earth itself acts as a large magnet, with a magnetic field strongest at its north and south magnetic poles. Other planets and the Sun also have magnetic fields extending into space.
Electicity and Magnetism Review
Magnetism is the attraction between magnets and other objects. Magnets have north and south poles and magnetic fields around them. Opposite poles attract while similar poles repel. In magnetic materials, magnetic domains contain clusters of atoms with aligned magnetic fields. Magnets can be ruined if heated or dropped, breaking them into smaller magnets. The Earth acts as a giant magnet with magnetic poles and fields, influencing compasses to point north.

Magnetism is caused by the alignment of electron spins in atoms. Natural magnets were first discovered in Magnesia, and the Chinese were the first to observe that magnetism could be induced in iron rods near these natural magnets. Michael Faraday established that changing magnetic fields induce electric currents based on electromagnetic induction. This principle led to technologies like generators and transformers that are crucial to modern electricity generation and distribution.

Magnetism is the force of attraction or repulsion between magnetic materials. Magnets usually have two poles - a North pole and a South pole. There are two types of magnets - permanent magnets that retain their magnetism, and temporary magnets that can be magnetized but lose their magnetism over time. Magnets can exert both attractive and repulsive forces on other magnets and some non-magnetic materials depending on whether the poles are the same or opposite.
Inside A Magnet
The document discusses magnetism at the atomic level. It explains that magnetic domains are groups of atoms whose magnetic fields are aligned, allowing some materials to become magnetized when most or all domains are similarly oriented. It provides examples of ferromagnetic materials like iron and cobalt that strongly exhibit magnetism due to aligned domains. Magnets can be made by placing unmagnetized ferromagnetic materials in strong magnetic fields or by rubbing them with magnet poles, and can be destroyed by impacts, heating, or breaking them into smaller magnet pieces.
Quantum mechanics
This document is a presentation on quantum mechanics by Primary Information Services. It discusses key topics of quantum mechanics including that electrons exist as standing waves around the nucleus rather than orbiting planets. It also mentions important applications of quantum theory like lasers, transistors and medical imaging. The document outlines the four quantum numbers that describe atomic structure and states that particles can pop into and out of existence at the quantum level due to energy and matter being interchangeable. It defines the quantum realm as where quantum effects become important at very small scales.
Magnetism Review
There are two types of magnets: permanent magnets that retain magnetic fields indefinitely, and temporary magnets that lose magnetic field strength over time or can be turned on and off. Materials that are naturally magnetic include iron oxide (magnetite/hematite) and some transition metals like iron, nickel, and cobalt. Electromagnets are temporary magnets that become magnetic under the influence of an electric current and are no longer magnetic when the current stops.
String Theory History
String theory began in the 1920s with Kaluza-Klein theory which proposed that electromagnetism can arise from gravity in a theory with four space dimensions. In the 1970s, string theory was developed as a way to describe the quantum mechanics of oscillating strings. Supersymmetry was introduced in the 1970s and holds the promise of resolving problems in particle theory. In the 1980s, string theory combined with supersymmetry yielded an equal number of fermions and bosons, showing it can be fully supersymmetric. Major advances in the 1990s included the duality revolution and using string theory to provide a microscopic explanation of black hole entropy.
Magnetism
The document discusses different forces including magnetism. It describes four fundamental forces: gravity, electromagnetic, strong force, and weak force. It then focuses on magnetism, explaining that it is a physical phenomenon produced by the motion of electric charge that results in attractive and repulsive forces. The document discusses magnetic field lines, electromagnets, naturally magnetic materials like iron and magnetite, and magnetic motors. It hypothesizes that magnetism may have an infinite range like gravity and that gravity may be a form of magnetism. Finally, it suggests that controlling forces could allow controlling the universe.
Magnetism
Magnetism arises from the movement of electrons within atoms. Magnets have north and south poles where opposite poles attract and similar poles repel each other, generating a magnetic field around the magnet. The magnetic field is the region of space around a magnet or electric current where its magnetic influence can be detected, with a magnet's north pole corresponding to geographic north.
String Theory
String theory is a theory that attempts to reconcile general relativity and quantum mechanics by proposing that fundamental particles are not zero-dimensional objects but are instead tiny vibrating strings. It describes all observed fundamental forces and matter without constants but instead involves many fields like the Higgs field, which can give particles mass when interacting with the field. String theory is needed to fully understand our universe at low energy levels and may help break the mystery of the strong nuclear force. It proposes that all strings are oscillating in up to ten dimensions, with their paths projected into our familiar three dimensions.
Magnetism e
The document discusses the earth's magnetic field and how it protects the planet. It describes how the earth's magnetic field deflects charged particles from the sun's wind away from earth, protecting life and infrastructure. These particles enter the magnetic field at the poles, where the field is strongest, and collide with gas molecules, ionizing them and causing them to emit light in the form of the auroras.

Grade 4 Science
The document discusses a grade 4 science lesson on sound. It introduces sound as vibrations, and has students do experiments to experience vibrations through a balloon and explore how the pitch of sounds changes based on the number and speed of vibrations by making sounds with bottles filled with different amounts of water. Key terms like vibrations, pitch, frequency are defined.
CBSE Class IX Sciense Physics Sound
Sound is a travelling wave that is an oscillation of pressure transmitted through a medium. Humans can hear sounds between 20-20,000 Hz. Sound speed depends on the medium and is faster in solids than liquids and gases due to closer particle packing. Noise is an unwanted sound that can cause hearing damage at high volumes. The ear detects sound waves which are then transmitted to the brain. Properties of sound waves include wavelength, amplitude, and frequency which determine pitch. Ultrasound has a frequency above human hearing range.
Physics Sounds.
Sound is composed of compression and rarefaction waves that the human ear can detect. It is produced by vibrations that create pressure variations in a medium and can be caused by either simple or complex motions. Sound waves carry energy and are longitudinal waves where the size of the compression indicates the energy. The human ear detects sound waves through the vibration of the ear drum which are then amplified by the bones and converted to nerve impulses in the cochlea. Properties of sound waves include pitch determined by frequency, loudness by amplitude, and timbre which distinguishes between sounds of the same pitch and loudness.
Presentation of science (sound)
The document discusses different aspects of sound including how it is produced, how it travels, and how the human ear perceives it. It defines sound as a mechanical wave that is an oscillation of pressure transmitted through a medium composed of frequencies within the range of human hearing. It describes that sound is produced by vibration and travels in waves, pushing and pulling on particles in the transmission medium. The human ear detects these pressure variations and converts them into electrical signals that are sent to the brain.
Sound and waves grade 6 pps
Sound is a form of energy that travels in longitudinal waves, requiring matter to transmit vibrations between particles. The speed of sound varies according to the medium, being fastest in solids and slowest in gases. Our ears can detect frequencies between 20-20,000 Hz, perceiving variations in pitch from low to high frequencies and loudness from soft to loud amplitudes. Musical instruments produce sound through vibration of different materials, while other technologies like sonar use sound waves for applications such as locating objects underwater.
Sound - Physics
A wave is a repeating disturbance that transfers energy through matter or space. There are two main types of waves - longitudinal waves, where the matter moves parallel to the direction of the wave, and transverse waves, where energy is transferred without transferring matter. Sound is a form of energy caused by vibrations that transfers through longitudinal waves. Key properties of waves include wavelength, frequency, amplitude, and speed. Sound waves can interfere constructively or destructively and be reflected, refracted, or absorbed.

The Nature of Magnetism: Electricity’s Silent Partner
Magnetism is a property of a material that enables to attract or repel other materials. The presence and strength of the material’s magnetic properties can be observed by the effect of the forces of attraction and repulsion on other materials.
What makes magnets?
Magnets are actually created by tiny spinning electrons in an atom. The electrons move about the nucleus and spin like a top, creating a tiny magnetic field.
If electrons are spinning in the same direction there is more magnetism, while electrons spinning in opposite directions cancel out each others’ magnetic fields. Magnetic fields are invisible, we can only see the effects of the magnetic force.

Magnets have two ends or poles, called north and south poles. At the poles of a magnet, the magnetic field lines are closer together.
The magnetic field lines around horse-shoe and disk magnets are closest together at the magnets’ poles. Unlike poles of magnets attract each other and like poles of magnets repel. Magnetic Poles: A region on a magnet which produces magnetic forces
The poles of a suspended magnet will align themselves to the poles of the Earth
Fundamental Rule: Like poles repel; opposite poles attract
If a force of attraction only is possible between an object and a magnet, then the object interacting with the magnet contains a ferromagnetic substance and is considered naturally magnetic.
If a force of repulsion is only between an object and a magnet, then the object interacting with the magnet may also be a permanent magnet or a temporarily magnetized ferromagnetic material.
Materials which are attracted by a magnet are known as magnetic materials. Iron, cobalt, nickel and many alloys of these metals like steel and alnico are magnetic.
Magnetic materials can be used to make permanent or temporary magnets unlike the non-magnetic materials which cannot.
INDUCED MAGNETISM
The process by which the screws become magnets is called Electric/Magnetic Induction. This same process is the reason why magnets attract non-magnetized magnetic substances such as the screw. The screw becomes an induced magnet with the end nearer the magnet having an opposite polarity to that of the permanent magnet. Hence attraction happens after magnetic induction occurs. The quicker way to know the polarity of a permanent or induced magnet is by the use of a magnetic compass. Compass needle is a small magnet that is free to pivot in a horizontal plane about an axis and that the end of the magnet that points to geographic north is called the north (N) pole. Likewise, the opposite end of the magnet is the south (S) pole.What are magnetic domains?
Magnetic substances like iron, cobalt and nickel
Interactive textbook ch. 18 sec 1 magnets & magnetism
Magnets have two poles, north and south, and exert magnetic forces on each other and other objects. Earth itself acts like a giant magnet, with its magnetic north pole located near its geographic south pole. Materials are magnetic if their atomic domains are aligned, allowing their magnetic fields to combine. There are different types of magnets including permanent and electromagnets. Earth's rotation creates electric currents in its liquid outer core, generating the planet's magnetic field.
Magnets
The document discusses the properties and uses of magnets. It describes several experiments that can be done to observe how magnets attract and repel different objects. It also explains key magnetic concepts like poles, magnetic fields, and how compasses detect the Earth's magnetic field. Permanent and temporary magnets are defined, and examples of how magnets are used in technology and medicine are provided.
Magnets
This document discusses how students will investigate magnets and how they attract and repel other magnets and common objects. Students will determine which materials are attracted to magnets, observe how magnets attract and repel each other, and understand that like poles repel and opposite poles attract. They will also observe magnetic field lines to predict if an object will be attracted or repelled by a magnet. The document provides a YouTube video and web game for demonstration and assessment.
24 5- 2014 final
This document provides information about magnets and magnetism. It defines a magnet, describes magnetism and the magnetic fields and lines of force. It explains the theories of magnetism including Weber's theory of molecular alignment and domain theory of electron spin. It discusses the applications of magnetism in nursing, including magnetic resonance imaging and associated safety issues related to static magnetic fields and contraindications for certain implants and medical devices. Nursing responsibilities regarding patient safety during MRI are reviewed.
Electricity and magnetism
This document discusses electricity and magnetism. It states that electricity is the flow of charged particles while magnetism is the force of attraction or repulsion between objects. In the 19th century, scientists realized there was a close relationship between electricity and magnetism, and discovered that a magnetic field could be created using an electrical current, a phenomenon known as electromagnetism. The document goes on to ask questions about electromagnets, magnetic and non-magnetic objects, and provides challenges about Benjamin Franklin's electricity experiments and Japan's Maglev trains.
Selina concise physics solutions class 6 chapter 6 magnetism
Magnets have two poles, north and south, and exhibit several key properties:
1) Like poles repel and unlike poles attract.
2) A freely suspended magnet will align itself north to south due to Earth's magnetic field.
3) Materials such as iron are attracted to magnets due to magnetic induction, the process by which a nearby magnet causes the material to take on its own magnetic properties.
FORCE (force and motion) (Teach)
Overview of force and how it is measured. Includes ideas of article charges, magnetism, simple electric motors and simple electric generators
Magnetism
The document discusses three ways to make a magnet: 1) Brushing, where a magnetic material is brushed with a magnet in one direction, creating opposite poles. 2) Flowing electric current, where a magnetic material has electric current passed through it in the same direction, creating an electromagnet. 3) Magnetic induction, where a magnetic material is brought near a strong magnet without touching, inducing opposite poles nearest the main magnet. The central concept in describing magnetic phenomena is the magnetic field.
Electricity and magnetism part 2
This document provides information about electricity, magnetism, and key figures that contributed to the understanding of these topics. It discusses Benjamin Franklin's famous kite experiment which demonstrated that lightning was electrical. It also introduces Hans Christian Oersted, a scientist who discovered the relationship between electricity and magnetism, paving the way for technologies like electromagnets. The document then explains different types of magnets, magnetic poles, magnetic fields, and how the Earth itself acts as a giant magnet with a molten iron core. It challenges students to research the aurora borealis in relation to the Earth's magnetism and explain the system of compasses as a navigational tool.
Ap2 unit5 open stax notes
1) Magnets have two poles, a north pole and a south pole. Like poles repel and unlike poles attract. Magnetic poles always occur in pairs and cannot be separated.
2) Ferromagnetic materials contain small magnetic regions called domains that act like magnets. In an external magnetic field, the domains align to strongly magnetize the material. Above the Curie temperature, ferromagnets lose their magnetism.
3) Electromagnets use electric currents to generate magnetic fields and act similarly to permanent magnets. They are widely used in applications requiring strong, controllable magnetic fields.
Magnetism
This document provides an overview of magnetism and magnetic fields. It discusses how magnets have been known for centuries and were used for navigation. It explains that all magnetic phenomena result from forces between electric charges in motion. It describes the properties of magnets including poles, magnetic fields, and how cutting a magnet produces two magnets. The document also discusses how the Earth itself acts as a magnet and how compasses use the Earth's magnetic field.
Magnetism short 2012
This document discusses magnetism and magnetic force. It explains that magnetism occurs within atoms when electrons and protons become aligned, creating polarity and magnetic force within certain materials like iron. It also describes how magnets have north and south poles where magnetic force is concentrated, and how opposite poles attract while similar poles repel. The document provides examples of objects magnets will and will not attract, and explains how electromagnets are made using electricity coiled around a metal core.
seeker 3 domain
Magnetism is caused by a physical field known as a magnetic field that is a property of some materials. It is not caused by evil spirits or spells. Magnetism occurs due to tiny regions within magnetic materials called magnetic domains that are magnetized in random orientations, canceling out the overall magnetic effect, or aligned, creating a bulk magnetic effect. Shielding items from magnetism can be done by placing them in a Faraday cage or wrapping them in a material that conducts electricity to divert magnetic field lines around the shielded object.
magnetism_qr.pptx
Magnets have north and south poles and are surrounded by magnetic fields, they exert attractive or repulsive forces on other magnets depending on whether the poles are opposite or alike, and an object is magnetic if the alignment of atomic domains within it create an overall magnetic field.
magnetism_qr.pptx
Magnets have north and south poles and are surrounded by magnetic fields, with the strongest forces occurring at the poles; the arrangement of atomic domains determines if a material is magnetic, with aligned domains creating magnetism; and while all magnets attract opposite poles and repel like poles, their magnetic properties can be enhanced, reduced, or changed through external influences on the domains.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
