Question

Under what condition is an electric current induced in a coil?

Options

• The number of magnetic lines of force passing through the coil changes.

• The number of magnetic lines of force passing through the coil remains constant.

• The coil is an open circuit with infinite resistance.

• Both the magnet and coil remain stationary.

Answer 1

A change in the magnetic flux passing through a coil produces induction. An electric current produced in a closed coil in this way is called the induced current.
