What happens when a magnet is broken in half?
Each half loses its magnetic properties.
One half remains a magnet, the other half does not.
Each half gains a new pole, becoming a separate magnet.
The magnet becomes too weak to attract any materials.
(a) causes the magnetic forces in magnets.
What can the force between magnets do?
Only push magnets apart
Only pull magnets together
Either push the magnets apart or pull them together
Neither push nor pull magnets
