South - North

Front

To increase the potential energy, would you 'spread them apart' or 'move them closer'?

Back

Spread them apart

Front

If you moved the magnet on the left closer to the magnet on the right, would you be moving the magnet 'With' or 'Against' the Magnetic Force?

Back

Front

What is a magnetic field?

Back

A region around a magnet where magnetic forces can be detected.

Front

What happens to magnetic field lines when two magnets are brought close together?

Back

They interact, either attracting or repelling each other.

Front

What is the direction of magnetic field lines?

Back

From the North pole to the South pole of a magnet.

Front

What is the effect of distance on magnetic force?

Back

The magnetic force decreases as the distance between magnets increases.

Front

What is the difference between permanent magnets and temporary magnets?

Back

Permanent magnets maintain their magnetism, while temporary magnets only exhibit magnetism in the presence of a magnetic field.
