When a loop of wire cuts magnetic lines of force, an electromotive force (EMF) is induced in the wire. This phenomenon is known as electromagnetic induction, and it is the basic principle behind generating electricity in generators and the functioning of electric motors. The induced current in the loop is proportional to the rate at which the magnetic lines of force are cut by the loop.

What is the difference between magnetic force and electric force?
Magnetic force is the force between magnets or moving charges, while electric force is the force between electric charges. Magnetic force acts on moving charges perpendicular to both the velocity of the charge and the magnetic field, while electric force acts along the line connecting the charges.
What is the imaginary line that helps us visualise a electric or magnetic field called?
The imaginary line that helps us visualize an electric or magnetic field is called a field line. These lines represent the direction of the force that a positive test charge would experience in the presence of the field.
What type of radiation deflected by the magnetic field?
Charged particles such as protons and electrons are deflected by a magnetic field. This deflection is known as the Lorentz force, which causes the particles to follow a curved path instead of a straight line.
What happens when a charged particle is moved along an electric field line?
When a charged particle is moved along an electric field line, it experiences a force in the direction of the field line. This force causes the particle to accelerate in the direction of the field line if the particle has the same charge as the field line, or decelerate if the charges are opposite.
Choose the best description of a magnetic field line A Magnetic field lines for a bar magnet are parallel to the magnet B A magnetic field line shows the direction a compass needle would?
B. A magnetic field line shows the direction a compass needle would align in a magnetic field.
What will happen when armature cuts a magnetic line of force?
When an armature cuts through a magnetic line of force, it induces an electromotive force (EMF) due to electromagnetic induction, as described by Faraday's law. This induced EMF generates an electric current if the circuit is closed. The direction of the induced current can be determined using Lenz's law, which states that it will flow in a direction that opposes the change causing it. This principle is fundamental to the operation of electric generators and motors.
What is the difference between magnetic force and electric force?
Magnetic force is the force between magnets or moving charges, while electric force is the force between electric charges. Magnetic force acts on moving charges perpendicular to both the velocity of the charge and the magnetic field, while electric force acts along the line connecting the charges.
Why iron filling line themselves up around the magnet?
Iron fillings align themselves around a magnet because the magnet creates a magnetic field that exerts a force on the iron filings. This force causes the iron filings to line up in the direction of the magnetic field, demonstrating the magnetic field lines.
What happens if the electron enters the magnetic field parallel to B?
If an electron enters a magnetic field parallel to the field lines (i.e., parallel to B), it will not experience any deflection or force due to the magnetic field. This is because the force on a charged particle moving parallel to a magnetic field is zero.
How do magnets attracts each other?
due to magnetic line of force. opposite pole present in magnets.
What is a line that cuts a segment in half?
A line that cuts a segment in half is a bisector
How do lines magnetic force travel?
from the magnet`s neutal lines to its poles. This is not correct. The path Magnetic Force Travels is always from it's North Pole around the Magnet to it's South Pole with completes the Magnetic Circuit. Then back through the magnet through the neuatral line back to its North Pole and starts again.
What is the imaginary line that helps us visualise a electric or magnetic field called?
The imaginary line that helps us visualize an electric or magnetic field is called a field line. These lines represent the direction of the force that a positive test charge would experience in the presence of the field.
What is the best description of a magnetic field line?
magnetic field line is an imaginary line showing magnetic energy between a north and south pole .
What Matter in which particles line line up pole to pole?
The type of matter in which particles are lined up pole-to-pole is magnetic. The poles help create the force from electricity.
What is the invisible force around a magnet called?
Have you ever seen a magnet? Did you see the field? There you go. While you can't see the field itself directly, you can see the effects of the field if you use iron filings or something like that; they'll line up with the magnetic field lines
Why do transmission lines possess inductance?
Transmission lines possess inductance due to the magnetic fields generated by the flow of electric current through the conductors. When current flows, it creates a magnetic field around the conductor, and the changing magnetic field induces an electromotive force (EMF) in the line, which is associated with inductance. Additionally, the physical separation between conductors in a transmission line contributes to the line's overall inductance, as the magnetic field interacts with the surrounding environment. This inductance affects the transmission line's impedance and the propagation of signals along the line.
