When a coil is rotated between two magnets, an electric current is induced in the coil due to the changing magnetic field. This phenomenon is known as electromagnetic induction. The induced current produces an electromagnetic force, creating a torque that causes the coil to rotate. This is the principle behind electric generators.

What happens when a coil is rotated between two magnets?
When a coil is rotated between two magnets, an electric current is induced in the coil due to the changing magnetic field. This phenomenon is known as electromagnetic induction and is the basic principle behind generators and electric motors. The amount of current induced depends on the speed of rotation and the strength of the magnetic field.
Why there is an induced current in a coil when a coil is rotated between two magnets?
When a coil is rotated between two magnets, the magnetic field lines cut across the coil, inducing an electromotive force (EMF) according to Faraday's Law of electromagnetic induction. This EMF creates an induced current in the coil as the electrons inside the coil are pushed in a direction that opposes the change in magnetic field, following Lenz's Law.
Why is there an induced current in a coil when a coil is rotated between two magnets?
When a coil is rotated between two magnets, the changing magnetic field induces a current in the coil according to Faraday's law of electromagnetic induction. As the coil cuts through the magnetic field lines, magnetic flux changes, causing an electromotive force and inducing a current in the coil. This current flows due to the presence of a closed path in the coil, generating an induced current.
Why does the coil rotates when it is placed in between two magnet?
When a coil is placed between two magnets, it experiences a force known as the Lorentz force. This force is a result of the interaction between the magnetic field of the magnets and the electric current flowing through the coil. As a result, the coil rotates due to the torque generated by this force.
Where do you use magnet to generate energy?
Magnets are used in generators to convert mechanical energy into electrical energy. When a magnet moves near a coil of wire, it induces an electric current in the wire through electromagnetic induction. This current can then be harnessed as electricity for various applications.

How alternating voltage is generated in a coil of wire when it is rotated between the poles of a magnet?
When a coil of wire is rotated between the poles of a magnet, it experiences a changing magnetic field. As a result, an electromotive force is induced in the coil of wire, leading to the generation of alternating voltage. This phenomenon is explained by Faraday's law of electromagnetic induction.
How do magnets help generator produce electricity?
Magnets would have magnetic flux around. As a coil linked with this magnetic flux is rotated such that the flux would change then an electro motive force is induced. This is the way in which generator functions.

Do magnets make electricity?
No. Magnets create an electric feild, not electricity.However, when you spin a magnet inside a coil of wire (or you can spin the coil of wire instead), you will create an electrical current.
Is there a difference between magnets and electromagnets?
Yes, magnets produce a magnetic field due to the alignment of the electrons in the material, while electromagnets produce a magnetic field when an electric current flows through a coil of wire. Magnets have a constant magnetic field, whereas electromagnets can have their strength controlled by adjusting the current.
Could you make a generator by mounting permanent magnets on a rotating shaft and keeping the coil stationary?
Yes, only relative motion between the coil and the magnetic field is important.
What force makes the coilgun work?
the force of objects being attracted by magnets. the coils or solenoids act as magnets and the projectile (which must be able to attract to magnets, often iron or steel is used) is attracted to the coils. but when the projectile reaches the coil the coil must be turned off so the projectile keeps going instead of stopping at the coil.
Can magnets produce electric currents?
Motion of a coil within a magnetic field will induce a current in the coil if it can complete a circuit.
