Question 117

Bar X is made of soft iron and Bar Y is made of steel. Both bars are placed inside separate solenoids connected to a direct current (d.c.) power supply to magnetise them. The current is then switched off in both solenoids. Which statement about the magnetic state of the bars is correct?

A

Both Bar X and Bar Y lose almost all of their magnetism.

B

Both Bar X and Bar Y retain most of their magnetism.

C

Bar X retains most of its magnetism, while Bar Y loses almost all of its magnetism.

D

Bar X loses almost all of its magnetism, while Bar Y retains most of its magnetism.
