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.

Answer. Two circular coils A and B are placed close to each other and If the current in the coil A is changed, then yes there will be some current induced in the coil B. This is so because of the magnetic field lines.
