: An [[electromagnet]] can be turned off and on.
: The strength of an [[electromagnet]] depends on; the number of coils of [[wire]], the [[Electrical Current|current]] through the [[wire]] and how easily the [[Soft Iron|soft iron]] core can be [[Magnetise|magnetised]].
*The more coils of wire the stronger the [[electromagnet]].
*The greater the [[Electrical Current|current]] through the [[wire]] the stronger the [[electromagnet]].
*The more easily [[Magnetise|magnetised]] the [[Soft Iron|soft iron]] core, the stronger the [[electromagnet]].

Changing the [[Electrical Current|current]] can change the strength of an [[electromagnet]].
An [[electromagnet]] can be turned on an off by turning the [[Electrical Current|current]] on and off.
The direction of the [[Magnetic Field|magnetic field]] can be changed in an [[electromagnet]] by changing the direction of the [[Electrical Current|current]].

[[Electromagnet]]s require a source of power to work.
[[Electromagnet]]s increase in [[temperature]] as they are used.
