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

Explanation

Yes , Current will be induced in coil B.
Reason : When the current in coil A is chaned , the magnetic field around it changes .
As the two circular coils (with their plances parallel to each other ) are placed close to each other , the magnetic field linked with coil B also change . Therefore , some current is induced in coil B .
