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.

Yes, current will be induced in the coil B. This happens because when current changes in A, the magnetic field produced by the current also changes. When the changing magnetic field is experienced by B it induces a current to oppose the field.

Two circular coil 'A' & 'B' are placed closed to each other. If the current in the coil 'A' is changed, then will some current be induced in coil 'B'. Explain.
Because of Electromagnetic Induction.
When the current change in 'A' then the magnetic field linked of the coil change as well.
Hence, the overall magnetic field around the coil 'B' also change.
