Magnets were first discovered around 4,000 years ago by a Greek shepherd named Magnets. Magnets can attract some metals but repel other magnets. They have two poles, a north and a south pole, and opposite poles attract while like poles repel each other due to magnetic forces. Magnets are used in many electronic devices and technologies to perform functions like generating motion or sorting recycled metals.
Lesson 14 magnets
Magnetism is the force that causes magnetic materials like iron, cobalt, and nickel to attract or repel each other. Materials that are not attracted to magnets, like paper and plastic, are called non-magnetic. A magnet has two poles, north and south, where the magnetic force is strongest. Magnets align themselves with the Earth's magnetic field when freely suspended. Magnets can attract metals through their magnetic force and repel other magnets or magnetic materials depending on whether the poles are the same or opposite.
Magnetism
This document discusses magnetism and magnetic substances. It defines three categories of substances: magnetic, ferromagnetic, and non-magnetic. Magnetic substances have their own magnetic field and can attract iron, cobalt, or nickel. Ferromagnetic substances are attracted to magnets but do not repel them, and must contain iron, nickel or cobalt. Non-magnetic substances are not attracted to magnets. All magnets have two poles, north and south, and opposite poles attract while like poles repel. The magnetic field around a magnet has directional lines of force from north to south. A compass works because its magnetic needle orients itself to be attracted to the south magnetic pole.

Electric Current and Magnetism
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.
Magnetic Field: The space around a magnet in which a magnetic force is exerted
— The shape of a magnetic field is revealed by magnetic field lines
Directed away from north poles and toward south poles
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
20 magnetism
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 ability of magnets to attract certain substances like iron. A shepherd named Magnes discovered magnetism when his iron stick got stuck to a stone on the ground. There are natural magnets found in nature called lodestones and artificial magnets that are magnetized artificially. Magnets have a magnetic field and properties like having two poles, attracting magnetic materials, and aligning in the north-south direction when suspended. Magnets are used for compasses, motors, speakers and lifting heavy loads. They can lose their magnetism through heating, hammering or improper storage.

This document discusses the heating effect of electric current. It explains that when electric current passes through a conductor, the conductor gets heated due to the flow of electrons. This heating effect is called Joule heating. Joule's law states that the amount of heat produced is directly proportional to the square of the current, the resistance, and the time. The document also provides an example calculation using Joule's law to determine the potential difference across a resistor given the heat produced, resistance, and time. Finally, it defines electric power as the rate at which electric work is produced or consumed in a circuit.
11_04 Units and Measurement.pptx
This document discusses different methods of measurement of length, large distances, small distances, and mass. It describes direct and indirect methods of measuring length using instruments like meter scales and Vernier calipers. It then explains the parallax method for measuring large distances between planets and stars from Earth by observing the angle of parallax. For small distances, it discusses using the parallax angle relationship between the basis and distance. Formulas are provided for calculating distance based on parallax angle and basis. Measurement techniques for small masses include using unified atomic mass units since masses of atoms and molecules cannot be measured in kg.
