===Meaning===
A '''magnet''' is a piece of [[equipment]] that can be used to do determine if an object a [[material]] is [[magnetic]].
: Singular [[Noun]]: '''Magnet'''
===About Magnets===
: '''Magnets''' are attracted [[attract]]ed to some metals. Those metals are '''magnetic''' but they are not magnets [[magnet]]s themselves.: '''Magnets''' have two [[poles]]; North and South.: When two North [[Poles ]] are placed next to each other two '''magnets''' will [[repel ]] each other.: When two South [[Poles ]] are placed next to each other two '''magnets''' will [[repel ]] each other.: When the North [[Poles|Pole ]] of one '''magnet''' is placed next to the South [[Poles|Pole ]] of another '''magnet''' they [[attract ]] each other.

===Meaning===
A '''magnet''' is an object that [[attract]]s [[Iron]], [[Cobalt]] or [[Nickel]].
===About Magnets===
: There are three types of [[magnet]] you should know:
*[[Permanent Magnet]]s - These are [[magnet]]s which have a permanent [[Magnetic Field|magnetic field]] which needs [[energy]] to be removed.
*[[Induced Magnet]]s - These are [[Magnetic Material|magnetic materials]] which only become [[magnet]]s when they are in the [[Magnetic Field|magnetic field]] of another [[magnet]].
*[[Electromagnet]]s - These are a coil of wire wrapped around a [[Soft Iron|soft iron]] core. They only become [[magnet]]s when there is a [[Electrical Current|current]] passed through the coil of wire.
: '''Magnets''' are [[attract]]ed to some [[metal]]s ([[Cobalt]], [[Nickel]] and [[Iron]]). Those [[metal]]s are '''magnetic''' but they are not [[magnet]]s themselves.
: '''Magnets''' have two [[poles]]; North and South.
: When two North [[Poles]] are placed next to each other two '''magnets''' will [[repel]] each other.
: When two South [[Poles]] are placed next to each other two '''magnets''' will [[repel]] each other.
: When the North [[Poles|Pole]] of one '''magnet''' is placed next to the South [[Poles|Pole]] of another '''magnet''' they [[attract]] each other.
: All [[magnet]]s have a [[Magnetic Field|magnetic field]] around them which influences other [[Magnetic Material|magnetic materials]].

===Meaning===
A '''magnet''' is an [[object]] that produces its own [[Magnetic Field|magnetic field]].

: '''Magnets''' are [[attract]]ed to some [[metal]]s ([[Cobalt]], [[Nickel]] and [[Iron]]). Those [[metal]]s are '''magnetic''' but they are not [[magnet]]s themselves.
: '''Magnets''' have two [[poles]]; North and South.
: When two North [[Poles]] are placed next to each other two '''magnets''' will [[repel]] each other.
: When two South [[Poles]] are placed next to each other two '''magnets''' will [[repel]] each other.
: When the North [[Poles|Pole]] of one '''magnet''' is placed next to the South [[Poles|Pole]] of another '''magnet''' they [[attract]] each other.
: The [[Earth]] is a [[magnet]] as evidenced by a [[Compass|magnetic compass]] lining up North to South everywhere on [[Earth]].
: All [[magnet]]s have a [[Magnetic Field|magnetic field]] around them which influences other [[Magnetic Material|magnetic materials]].
: A [[magnet]] is made of several small [[Magnetic Domain|magnetic domains]] which are regions in the [[magnet]] which act as smaller [[magnet]]s.

| style="height:20px; width:200px; text-align:center;" |When [[Magnetic Domain|magnetic domains]] are aligned the [[object]] has an external [[Magnetic Field|magnetic field]] so it acts like a [[magnet]].
