Question

State true or false. A current is induced in the coil when the number of magnetic lines of force associated with a coil change.​

Answer 1

Answer:

True

Explanation:

When the two circular coils are placed close to each other, when a current in coil A changes, the magnetic field associated with it also changes. As a result magnetic field around coil B also changes. This change in magnetic field lines around coil B induces an electric current in it.

Answer 2

True

Hope it works
