Explain mutual induction

Answer 1

Mutual induction is the phenomenon in which a changing current in one coil of wire induces a voltage in a nearby coil of wire. This occurs when the magnetic field produced by the changing current in the first coil interacts with the second coil, causing an electric current to flow in the second coil.

The amount of voltage induced in the second coil depends on the rate of change of the current in the first coil, as well as the number of turns in each coil and the distance between the coils. This process is fundamental to the operation of transformers and other devices that use electromagnetic induction to transfer energy from one circuit to another.

Mutual induction plays a crucial role in the transmission and distribution of electricity, as it allows for the efficient transfer of energy over long distances without the need for direct electrical connections. It is also utilized in devices such as electric motors, generators, and inductive sensors.
