Question

What can produce a current in a coil even when the coil does not move?

Options

• A magnet moves relative to a coil

• A coil moves away from a solenoid

• A coil is moved in front of a solenoid

• A coil moves in the magnetic field of a magnet

Answer 1

A magnet moving relative to a coil can produce current without moving the coil. The motion changes the magnetic field passing through the coil.
