Question 31
H

A student writes three statements about the force on a wire in a magnetic field.

Statement 1: A copper wire carrying a current is pushed by a magnet because copper is a magnetic material.

Statement 2: The force on a wire carrying a current is largest when the wire is parallel to the magnetic field.

Statement 3: When a wire carrying a current is pushed by a clamped magnet, there is no force on the magnet, because the magnet does not move.
