==Key Stage 3==
===Meaning===
A '''permanent magnet''' is an [[object]] with its own [[Magnetic Field|magnetic field]] that remains there even when there are no other external [[Magnetic Field|magnetic fields]].
===About Permanent Magnets===
: A [[Bar Magnet|bar magnet]] is a '''permanent magnet'''.
: '''Permanent magnets''' are used in a electrical [[D.C. Motor|motor]]s.
==Key Stage 4==
===Meaning===
A '''permanent magnet''' is an [[object]] with its own [[Magnetic Field|magnetic field]] that remains there even when there are no other external [[Magnetic Field|magnetic fields]].
===About Permanent Magnets===
: A [[Bar Magnet|bar magnet]] is a '''permanent magnet'''.
: '''Permanent magnets''' are used in a electrical [[D.C. Motor|motor]]s.
: A '''permanent magnet''' can only lose its [[Magnetic Field|magnetic field]] under certain conditions:
*When it is struck with a sudden [[force]].
*When it is [[heated]].
*When an extremely strong external [[Magnetic Field|magnetic field]] is applied.
