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

Q. No 14: 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.

Ans:  If the current in the coil A is changed then some current will definitely be induced in the coil B. When the current in coil A is changed, the magnetic field associated with it also changes. As a result, the magnetic field around coil B also changes. This change in magnetic field lines around coil B induces an electric current in it. This process is known electromagnetic induction.

  3. I HAVE DOUBT, I THINK CURRENT IS INDUCED ONLY WHEN THERE IS SOME FORCE, IN THIS THIS CASE THERE IS NO FORCE APPLIED THEN HOW CURRENT IS INDUCED IN COIL B

    1. Yeah, your question is good but the thing is that the current is changed in coil B because the magnetic fields of these two coils i.e. A & B are very much close to each other. I hope you got your answer.
