Magnetism is the attraction between magnets and other objects. Magnets have north and south poles and magnetic fields around them. Opposite poles attract while similar poles repel. In magnetic materials, magnetic domains contain clusters of atoms with aligned magnetic fields. Magnets can be ruined if heated or dropped, breaking them into smaller magnets. The Earth acts as a giant magnet with magnetic poles and fields, influencing compasses to point north.

Magnetism

3. Magnetism
Magnetism is the attraction of a magnet for another object.

4. Poles
Magnets are strongest at the poles
The north pole repels the other north poles but attracts the south
poles.

5. Magnetic Fields
The area of Force around a magnet is know as magnetic Fields.

6. Magnets
Opposites attract while similar poles repel.

7. Magnetic Domains
In a magnetic material most of the clusters of billions of atoms,
or magnetic domains, have magnetic fields that are lined up in
the same way.
Magnetic Domains- clusters of billions of atoms that have a
magnetic field that are lined up parallel in the same way.
