A magnet consists of a north pole and a south pole, which are the strongest parts of a magnet. When same poles of the magnet (north pole and north pole; south pole and south pole) are close to each other, magnetic force of replusion occurs, which pushes the magnets away from each other. If opposite poles (north pole and south pole) are close to each other, force of gravity occurs, which attracts the magnets towards each other.
Science Learning Objectives:
- Recognise that a magnet can exert a push or a pull.
- Identify the characteristics of magnets: a freely suspended bar magnet comes to rest pointing in a North-South direction; unlike poles attract and like poles repel; magnets attract magnetic material.
- List some uses of magnets in everyday objects.
