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 inducted in the coil b give reason

Answer 1

Explanation:

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.

Answer 2

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.
