Two circular coils A and B are placed close to each other. If the current in the coil A is changed, will some current be induced in the coil B? Give reason.

Explanation

Two circular coils A and B are placed closed to each other. When the current in the coil A is changed the magnetic field associated with it will also change.
This change in magnetic field lines around coil B induces a current in it. That is called Electro-magnetic Induction.
