The part of a magnet that is attracted to the south–seeking pole of another magnet, and to Earth's magnetic North Pole.

A material that is attracted to a magnet. The elements iron, cobalt and nickel, and their alloys (such as steel), are magnetic; non–metals and other metals are not magnetic.

A tiny magnet in a compass that freely turns to line up with the direction of a magnetic field.

A line with an arrow, showing the direction in which a force acts on the north–seeking pole of a magnet in a magnetic field.

In the Magnets and electromagnets unit, pupils learnt about rules for magnets, magnetic fields of bar magnets, and the properties and uses of electromagnets. 

This unit explores magnetism, including permanent and induced magnets, magnetic fields, and Earth's magnetism. It covers current-induced magnetic effects, electric motors, and devices like microphones and loudspeakers, with an emphasis on models, calculations, and practical applications.

An insulated wire wound into the shape of a spring.

Very pure iron that cannot be made into a permanent magnet.

Describes the relationship between two variables, in which doubling the value of one variable doubles the value of the other.

These show the accuracy of each measurement on a graph.

A magnet made by running current through a coil of wire round an iron core.

An electromagnet that loses its magnetism when current stops flowing through it.

A lock that can be opened with an electromagnet when a switch is closed.

A bell that uses an electromagnet to strike a clapper on the bell and which resets itself to keep ringing.

A motor that uses a magnetic field to produce a force.

is a material that does not conduct electric current

a coil of insulated wire that spins inside an electric motor when a current flows through it

a rod at the centre of wheels and gears around which they turn

in a motor kit, a U–shaped piece of iron that holds two magnets in place to create a uniform magnetic field
