1. Forces can change the motion of objects by moving stationary objects, changing the speed or direction of moving objects, or deforming objects. Balanced forces do not change motion while unbalanced forces do.
2. Friction opposes the motion of objects over a surface. Galileo's experiments with inclined planes showed that the motion of objects depends on the balance of forces.
3. Newton's laws of motion state that objects remain at rest or in uniform motion unless acted upon by an unbalanced force, the acceleration of an object depends on the net force acting on it and the object's mass, and for every action there is an equal and opposite reaction.

1. Michael Faraday discovered electromagnetic induction in 1831, showing that a changing magnetic field can generate an electric current.
2. An electric motor works by placing a coil of wire between the poles of a magnet. When current passes through the coil, it experiences a force due to the magnetic field and begins to rotate, converting electrical energy to mechanical energy.
3. Key parts of a motor include an insulated copper wire coil, magnet poles to provide a magnetic field, split rings acting as a commutator to reverse current direction, an axle for the coil to rotate around, and brushes connecting the commutator to a current source.
Magnetic Effects of Electric Current
1. Hans Christian Oersted discovered that an electric current produces a magnetic field around it. The direction of the magnetic field depends on the direction of current flow.
2. A straight current-carrying conductor produces concentric circular magnetic field lines around it. A circular loop or solenoid produces parallel magnetic field lines similar to a bar magnet.
3. The magnetic field produced is directly proportional to the current and inversely proportional to the distance from the conductor. It is also affected by the number of turns in a coil.
The document discusses the magnetic effects of electric currents. It describes how Hans Christian Oersted discovered in 1820 that a compass needle is deflected near a current-carrying wire, showing that electric currents produce magnetic fields. It explains that a compass or magnet can detect the magnetic field surrounding another magnet or a current-carrying conductor.
Magnetic effects can be produced by electric currents. When a current flows through a conductor, it creates a magnetic field around the conductor. Three key relationships govern magnetic fields: (1) like magnetic poles repel and opposite poles attract, (2) the strength of a magnetic field depends on the amount of current and number of turns in a coil, and (3) changing magnetic fields can induce electric currents in nearby conductors based on Lenz's law. Electromagnets and transformers take advantage of these relationships to manipulate magnetic fields for applications like motors, generators, and power transmission.
The document discusses electromagnetism and various electromagnetic concepts. It begins by explaining that electromagnetism is the phenomenon where electricity creates magnetism. It then discusses how a simple electromagnet works using a battery, wire, and nail. The direction of the magnetic field is determined using the right hand grip rule and Maxwell's screw rule. A solenoid, which is a long coil of wire, is introduced and how its magnetic field is similar to a bar magnet but passes through its axis. Factors affecting magnetic field strength, such as number of turns and current, are covered. The document also discusses force on a current-carrying conductor in a magnetic field using Fleming's left hand rule. It concludes by covering
This document provides an overview of basics of electrical engineering, specifically focusing on magnets and magnetism. It defines different types of magnets including permanent magnets, temporary magnets, and electromagnets. It describes magnetic domains, magnetic dipoles, magnetic fields, flux, and various laws of magnetism including Biot-Savart law, Ampere's law, force law, and Faraday's law. It also discusses applications such as solenoids, transformers, and generators.
Magnets have north and south poles and magnetic fields that emerge from the north pole and return through the south pole. Molecular theory states that magnetism arises from electron orbits within molecules acting as tiny molecular magnets that are aligned in magnetized materials. An electric current flowing through a wire produces a circular magnetic field around it according to the right-hand rule. A coil of wire with current induces a magnetic field within it with field lines parallel to its axis. Electromagnets use this principle, with a solenoid wrapped around an iron core that becomes magnetized when current flows through the coil.
Magnets have north and south poles and magnetic fields created by electron arrangement. Molecular theory explains magnetism at the atomic level, with molecular magnets aligning in materials. Electric currents create magnetic fields, demonstrated by patterns with iron filings. Electromagnets are coils that can be magnetized and demagnetized by switching current on and off. Moving coil meters like the milliammeter measure current through magnetic interactions between the coil and a permanent magnet.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
How to Make a Field Mandatory in Odoo 17Celine George
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.

2. Magnets
A substance which attracts small pieces of iron and points in North-South
direction when suspended freely in known as Magnet. A naturally occurring
iron ore which is called loadstone or magnetite also behaves as a magnet but it
is a very weak magnet. The ones we see are made from them in artificial way
and permanent and strong.
Properties of magnet:-
1)Has 2 poles- North and South.
2)Like poles repeal each other and unlike poles attract each other.
3)They always exist in pairs of poles.
4)Repulsion is the only sure test for a magnet.
3. Magnetic Field and Field Lines
a) Magnetic field
The region around a magnet where the force of attraction or repulsion can be
detected is called magnetic field. Magnetic field around a magnet can be
detected by using a magnetic compass.
4. b)Magnetic field lines
Magnetic field lines are the paths around a magnet along which the north pole
of a magnetic compass needle tends to move.
The magnetic field lines around a magnet can be observed by sprinkling iron
filings around a magnet. It can also be observed by moving a magnetic
compass around a magnet.
i) The magnetic field lines emerge at the north pole and merge at the
south pole.
ii) The magnetic field lines are closer at the poles.
iii) The magnetic field lines do not intersect each other.
5. Magnetic Field Due to Current Carrying
Conductor
If a magnetic compass is placed near a conductor carrying current (wire), the
needle is deflected. This shows that a conductor carrying current has a
magnetic field around it.
If the direction of the current is from north to south, the deflection of the
magnetic needle is towards the east. If the direction of the current is from
south to north, the deflection of the needle is towards the west. The magnetic
field around a current carrying straight conductor is in concentric circles. It
can be observed by passing a current carrying straight conductor through a
cardboard and sprinkling iron filings on it.

W E
6. Right Hand Thumb Rule
The direction of the magnetic field around a conductor is given by the Right Hand
Thumb Rule.
It states that ‘ If a current carrying conductor is held in the right hand such that
the thumb points in the direction of current, then the fingers wrapped around the
conductor shows the direction of the magnetic
field ’.
7. Magnetic Field Due to Current in Circular Loop
When current is passed through a circular conductor (loop) the
magnetic field produced is in the form of concentric circles around
the conductor. Towards the centre the arcs of the circles become
larger and appears as straight line.
8. Magnetic Field Due To Current in a Solenoid
A solenoid is a circular coil of wire in the shape of a cylinder.
When current flows through a solenoid, it behaves like a bar magnet. The ends
of the solenoid behaves like the North and South poles of a magnet. The magnetic
field produced by a solenoid is similar to the magnetic field produced by a bar
magnet.
The strength of the magnetic field depends upon the strength of the current and
the number of turns of the coil.
9. Electromagnet
A strong magnetic field inside a solenoid can be used to magnetise a piece
of magnetic material like a soft iron when placed inside the coil. Such a
magnet is called an electromagnet.
If electric current is passed through a wire wound around a piece of soft
iron, it behaves like a magnet. Such a magnet is called an electromagnet.
10. Force on a Conductor Carrying Current In
Magnetic Field
A.M.Ampere suggested that if a current carrying conductor produces a magnetic
field and exerts a force on a magnet, then a magnet should also exerts a force on a
current carrying conductor.
Eg :- If an aluminium rod is suspended horizontally by a wire between the poles of
a horse shoe magnet and current is passed through the wire, then the aluminium
rod is displaced. If the direction of current is reversed, the direction of
displacement is also reversed. The force exerted is maximum if the conductor is
perpendicular to the magnetic field.
11. Fleming’s Left Hand Rule
The direction of force (motion) of a current carrying conductor in a magnetic
field is given by Fleming’s Left Hand Rule.
It states that ‘ If we hold the thumb, fore finger and middle finger of the left
hand perpendicular to each other such that the fore finger points in the direction
of magnetic field, the middle finger points in the direction of current, then the
thumb shows the direction of force (motion) of the conductor’.
12. Electromagnetic Induction (Michael Faraday)
The motion of a magnet with respect to a coil or a change in the magnetic field
induce a potential difference in the coil and produces induced current. This is
called electromagnetic induction.
i) Motion of a magnet with respect to a coil produces induced current :-
If a magnet is moved towards or away from a coil of wire connected to a
galvanometer, the galvanometer needle shows a deflection. This shows that
current is induced in the coil due to the motion of the magnet.
13. ii) Change in magnetic field produces induced current :-
Take two coils of wires wound around a cylindrical paper roll. Connect one coil
to a battery and the other coil to a galvanometer. If current is passed through the
first coil, the galvanometer needle shows a deflection in the second coil. If the
current is disconnected, the needle moves in the opposite direction. This shows
that current is induced due to change in magnetic field.
Coil -1 Coil - 2
14. The direction of induced current is given by Fleming’s Right Hand Rule.
It states that ‘ If the thumb, fore finger and middle finger of the right hand
is held perpendicular to each other such that the thumb points in the
direction of motion of the conductor, the fore finger points in the direction
of the magnetic field, then the middle finger shows the direction of induced
current ’.
15. Direct & Alternating Current
a) Direct current (DC) :- A current that always flows in one direction
only is called direct current.
The current we get from a battery is a direct current.
b) Alternating current (AC) :- A current that reverses its direction
periodically is called alternating current.
Most power stations in our country produce alternating current. AC
changes direction every 1/100 second and its frequency is 50 Hertz
(Hz).
One advantage of AC over DC is that it can be transmitted over long
distances without much loss of energy.

16. Domestic Electric Circuit
Earth wire Distrbution box
with main switch
and fuses
Electric power to homes is supplied through the mains. It has two wires. One is a live
wire (positve wire) with red insulation and the other is a neutral wire (negative wire)
with black insulation. The potential difference between the two wires is 220V. The earth
wire with green insulation is connected to a metal plate kept in the ground.
Two separate circuits are used. One is of 15A for appliances with high power rating like
geysers, air conditioners etc. The other is of 5A for fans, bulbs etc. The different
appliances are connected in parallel so that every appliance gets equal voltage and even
if one is switched off the others are not affected.
The appliances having metallic body like electric iron, refrigerators etc., their metallic
body is connected to the earth wire so that if there is leakage of current, it passes to the
earth and prevents electric shock.

17. Electric Fuse
Electric fuse is a safety device used in electric circuits to protect the circuit and
appliances from damage due to overloading and short circuit. It is a wire having
high resistance and low melting point. If excess current flows through the circuit,
the fuse wire melts and breaks the circuit. Fuse wire is made of a metal or an
alloy of metals like lead, tin, aluminum and copper. Fuse wire is connected in
series with the live wire.
OVERLOADING
Overloading is caused due to increase in voltage, or if the live wire and neutral
wire comes in contact or if too many appliances are connected to a single socket.
It results in overheating of the wires and can cause damage to the circuit and
appliances.
SHORT CIRCUIT
Short circuit is caused when the live wire and neutral wire comes in contact and
the current suddenly increases in the circuit. It causes spark, fire and damage to
the circuit and appliances.
