Question

1)Explain the phenomenon of an electromagnetic induction.
2)Explain how a torque is produce on a coil in magnetic field
3) Explain Faraday's law, Self inductance and mutual inductance

Answer 1

It can be easily understood from you tube vdos like from smart learning for all...

Answer 2

1. when current is passed through a coil and due to its magnetic effect current is produce in another coil such phenomenon is known as electro magnetic induction.
2. torque is produce as due to the spinning of coil.
3. Faraday's law says that when current is passed through a coil it produces magnetic field and when another coil is taken near it due to magnetic field current get introduce in second coil also this current is known as induced current.
