Magnetic Terminology

Term Description
Anisotropic: Has a preferred direction of magnetism (axis). Once magnetised the direction of magnetism cannot generally be changed.
Isotropic: Can be magnetised in any direction since it has no preferred direction (axis) of magnetism.
Northpole: Defined as the end of the magnet which seeks the geographical north pole (except in magnet therapy terminology - where the north pole attracts the 'north facing' needle of a compass i.e. seeks the geographical south pole).
