What happens to the force between two magnets as the distance between them increases?

Back

The force between two magnets decreases as the distance between them increases.

Front

What do the lines around a magnet represent?

Back

The lines around a magnet represent the magnetic field.

Front

How can a wire become magnetic?

Back

A wire can become magnetic by running a current through it.

Front

What type of magnet can be turned on and off?

Front

If the North Pole of a permanent magnet is placed next to a compass, which direction will the needle move?

Back

The needle will move counter-clockwise.

Front

Define magnetism.

Back

Magnetism is a physical phenomenon produced by the motion of electric charge, which results in attractive and repulsive forces between objects.

Front

What is a permanent magnet?

Back

A permanent magnet is a material that maintains a persistent magnetic field without the need for an external power source.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

What is the magnetic field?

Back

The magnetic field is the region around a magnet where magnetic forces can be detected.

Front

What is the difference between the North Pole and South Pole of a magnet?

Back

The North Pole of a magnet is the end that points towards the Earth's geographic North, while the South Pole points towards the Earth's geographic South.
