Study Notes
Properties of Magnets
- A magnet is a material that attracts iron or materials containing iron.
- All magnets have two poles, known as the north pole and the south pole.
- One end of the magnet, the north pole, always points to the north.
- The opposite end of the magnet, the south pole, points to the south.
Magnetic Poles
- Magnetic poles are always found in pairs, one north and one south.
- If a magnet is broken in half, each half will gain a new pole, resulting in two complete magnets.
Magnetic Force
- Magnets exert forces on each other when brought close together.
- The magnetic force results from electric charges in the magnets, created by gaining or losing electrons.
- The force between magnets can either push them apart or pull them together.
- The magnetic force depends on the alignment of the poles of the magnets.
