==Key Stage 3==
===Meaning===
An '''induced magnet''' is an [[object]] that only has its own [[Magnetic Field|magnetic field]] when it is in another external [[Magnetic Field|magnetic field]].
===About Induced Magnets===
: [[Object]]s made of [[pure]] [[Iron]] can be '''induced magnets'''.
: '''Induced magnets''' are used as the core of [[electromagnet]]s.
==Key Stage 4==
===Meaning===
An '''induced magnet''' is an [[object]] that only has its own [[Magnetic Field|magnetic field]] when it is in another external [[Magnetic Field|magnetic field]].
===About Induced Magnets===
: [[Object]]s made of [[pure]] [[Iron]] can be '''induced magnets'''.
: '''Induced magnets''' are used as the core of [[electromagnet]]s.
: A [[magnet]] is made of several small [[Magnetic Domain|magnetic domains]] which are regions in the [[magnet]] which act as smaller [[magnet]]s. In an '''induced magnet''' these [[Magnetic Domain|magnetic domains]] can be easily changed so that if an external [[Magnetic Field|magnetic field]] is applied they will all line up in the same direction.
