Question 30
H

An unmagnetised iron bar is placed in the magnetic field of a strong magnet. What happens to the magnetic field in the region around the iron bar?

[1]
A

The field is unchanged, because the iron bar stays unmagnetised

B

The field is cancelled, so there is no magnetic field near the bar

C

The field is reversed, so it points the opposite way near the bar

D

The field is changed, because the iron becomes an induced magnet
