Which test could be used to find which end of the magnet is north pole?

A student has a bar magnet. He brings the magnet close to an object. The magnet and the object repel each other. What is the other object made from?

Which of these is not a magnetic material?

Which of the above diagrams shows the magnetic field lines around the north pole of a magnet?

When magnets and metal bars are close together they experience forces.

Which row gives the correct description of the effect between these materials?

A magnetic compass points North. This shows that...

A magnetic field line shows the direction of force acting on

A uniform magnetic field can be produced between 2 permanent magnets. Which of the following arrangements of magnets will produce the field shown?

Some magnets are easily magnetised when placed in a magnetic field, and then quickly lose their magnetism once the field is removed. These materials are used in electromagnets, and are called...

The diagram shows the magnetic field around two bar magnets.

Which diagram shows the poles of the magnets?

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?

Two nickel bars are placed close to the N-pole of a bar magnet. The nickel bars become magnetised.

Which row 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?

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?

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.

The top three diagrams show what happens when there is a current in the coils.

The three diagrams in the second row below show what happens when the current is then switched off in each coil.

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

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?
