Question 7
H

A magnet is pulled out of a coil that forms part of a complete circuit. A current is induced. Which statement about the magnetic field of the induced current is correct?

[1]
A

It acts with the field of the magnet, so the magnet is easier to pull out

B

It acts with the field of the magnet, so the magnet is harder to pull out

C

It opposes the change in the field, so the magnet is easier to pull out

D

It opposes the change in the field, so the magnet is harder to pull out
