Back

A region in a magnetic material in which the magnetic fields of atoms all point in the same direction.

Front

How do magnetic field lines move?

Back

Always from the north pole towards the south pole.

Front

What does the strength of a magnetic force depend on?

Front

What materials are considered magnetic materials?

Back

A magnet that maintains its magnetic properties without the need for an external magnetic field.

Front

What is an electromagnet?

Back

A type of magnet in which the magnetic field is produced by an electric current.

Front

What happens to a magnet when it is heated?

Back

It can lose its magnetism due to the increased thermal energy disrupting the alignment of magnetic domains.
