→About Magnets
*[[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.
