Question 15 • Physical Science

A current is induced in a wire by moving the wire through a magnetic field. Which is one factor that affects the direction of the current?

Answer
A
the type of magnet
B
the direction of the needle on an ammeter
C
the direction in which the wire moves
D
the thickness of the wire

Explanation

The direction of the induced current depends on the direction the wire moves through the magnetic field. Reversing the wire’s motion reverses the direction of the induced current. The ammeter needle shows the current’s direction; its direction does not cause it.
