Key Stage 2
Meaning
Magnetism is a force that causes magnets to be attracted or repelled from one another.
- Noun: Magnetism
About Magnetism
- Magnetism is a non-contact force.
- Magnetism only affects certain materials:
- Iron
- Steel
- Cobalt
- Nickel
 |
| Magnetism only affects these metals. |
- Magnetism can be attractive or repulsive.
 |
| Two magnets facing North-North will repel each other and two magnets facing South-South will repel each other. |
 |
| Two magnets facing North-South will attract each other. |
Key Stage 3
Meaning
Magnetism is a force that affects magnetic objects in a magnetic field.
About Magnetism
- Magnetism is a force so it is measured in Newtons.
- Magnetism is a non-contact force because it can act without objects touching.
- Magnetism can be attractive when two opposite poles are near one another or repulsive when two 'like' poles are placed near one another.
- Magnets produce a magnetic field. If Iron,Cobalt or Nickel are in that magnetic field they will be attracted to the magnet.
