Magnetism

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
MagneticMetals.gif
Magnetism only affects these metals.
Magnetism can be attractive or repulsive.
MagnetRepel.gif
Two magnets facing North-North will repel each other and two magnets facing South-South will repel each other.
MagnetAttract.gif
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.
