Two circular coils A and B are placed closed to each other, if the current in the coil A is changed, will some current be induced in the coil B? Give reason for your answer.
Two circular coils A and B are placed closed to each other, if the current in the coil A is changed, will some current be induced in the coil B? Give reason for your answer.

Answer:

Because of the shift in the magnetic field caused by the placement of coils B and C in close proximity to each other, the other coil will experience some current induced into it. Electromagnetic induction is the term used to describe this phenomenon.
