MagnetismThe attraction of a magnet for another

object

AttractionWhen two magnets or magnetic objects are close to each other, there is a force that attracts the poles together

RepulsionWhen two magnetic objects have like poles facing each other, the magnetic force pushes them apart.

Magnetic Pole

The area of a magnet where the effect is the strongest. The magnetic field is strongest at the poles of a magnet. It allows magnets to be attracted to each other without touching

Magnets may be cut in half, but each piece maintains its magnetic properties
