Question 25
H

Bar P and bar Q look the same. One of them is a permanent magnet and the other is unmagnetised steel. A student holds one end of bar P against the middle of bar Q. There is almost no force between them. Which conclusion is correct?

[1]
A

P is the permanent magnet, because its field is weakest at its end

B

Q is the unmagnetised bar, because it has no poles in its middle

C

Q is the permanent magnet, because its field is weakest at its middle

D

P is the unmagnetised bar, because its end cannot become magnetised
