Two nickel bars are placed close to the N-pole of a bar magnet. The nickel bars become magnetised. Which row in the table states the pole induced at P, the pole induced at Q, and the type of magnetic force between P and Q?

A student wishes to make a permanent magnet. She has an iron rod and a steel rod. Which rod should she use to make the permanent magnet, and is this rod a hard magnetic material or a soft magnetic material?

Which statement about magnetism is correct?

In which pair are both materials magnetic?

The diagram shows the magnetic field around two bar magnets. Which diagram below correctly shows the poles of the magnets?

The diagram shows apparatus that can be used to make a magnet. Which metal and which power supply are used to make a permanent magnet?

A wire perpendicular to the page carries an electric current in a direction out of the page. There are four compasses near the wire. Which compass shows the direction of the magnetic field caused by the current?

Which group contains only non-ferrous metals?

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. What do the soft-iron nails do as the switch is closed, and what do they do when the switch is then opened?

Which action will demagnetise a magnetised piece of steel?

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?

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?

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

Which procedure may be used to demagnetise a steel bar?

Which statement about a permanent bar magnet is correct?

The diagram shows two magnets and two iron rods placed in a line. Which magnetic poles are induced at the ends J and K of the iron rods?

Two iron nails hang from a bar magnet. Which diagram shows the magnetic poles induced in the nails?

The ends of three metal rods are tested by holding end Q of rod 1 close to the others in turn. The results are as follows. End Q: attracts end R, attracts end S, attracts end T, repels end U. Which of the metal rods is a magnet?
