Question 11
H

A student writes three statements about electromagnetic induction.

Statement 1: A current is induced in a coil whenever there is a magnet inside the coil.

Statement 2: A potential difference is only induced across a wire moving through a magnetic field if the wire is part of a complete circuit.

Statement 3: Moving a coil towards a stationary magnet does not induce a current, because it is the magnet that must move.
