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

Explanation

Yes, if current is changed in coil A, current is induced in coil B. When the current in coil A is changed, the magnetic field around it also changes. As the coil B is placed very close to the coil A, the magnetic field lines around coil B also change and so, current is induced in it.
