Question

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??​

Answer 1

ANSWER : Yes, when a current in coil A changes, magnetic field lines linked with coil B also change. Hence, due to change in number of magnetic field lines, there is an induced current in coil B

Answer 2

Answer:

Two circular coils A and B are placed close to each other. 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 is called electromagnetic induction.
