Induced Magnetism

A magnetic material will temporarily become a magnet when it is close to a permanent magnet. There is always an attractive force between an induced magnet (or magnetic material) and a permanent magnet.

Induced magnetism

Induced magnetism

  • Induced magnets are magnetic materials that become magnets when they are in a magnetic field.
  • When moved away from the permanent magnet, the magnetic material will stop being a magnet.
  • This is called induced magnetism.
Poles

Poles

  • The permanent magnet induces (creates) temporary poles in the magnetic material and these align so that the magnetic material is attracted to the permanent magnet.
  • If the north pole of the magnet is next to the magnetic material, then a south pole will be induced in the part of the material closest to the magnet.
