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.

Dear Student


The current if changed in coil A. Some current will be induced in the coil B.

Reason: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 B coil also changes due to this as current is induced in it.

Thanks
