An electromagnet with a soft-iron core is connected to a battery and an open
switch. The soft-iron core is just above some small soft-iron nails.
The switch is now closed, left closed for a few seconds, and then opened.

A student investigates the force on a bar magnet placed near a current-carrying coil. She carries out three different experiments.

In experiment 1, the magnet is attracted to the coil.

Which row shows what happens in the other two experiments?

1

Three cores of different metals, P, Q and R, are placed inside identical coils of wire. At least one of the metals is non-ferrous. The cores are held above some iron nails.

Which choice correctly identifies whether the core metals are ferrous or non-ferrous?

1

Which choice correctly states whether each metal is ferrous or non-ferrous?
