: When there is a [[Electrical Current|current]] in a [[wire]] the [[wire]] has a [[Magnetic Field|magnetic field]] which acts around that [[wire]].

*The [[Electrical Current|current]] in the [[wire]] - The greater the [[Electrical Current|current]] the stronger the [[Magnetic Field|magnetic field]].

*The distance from the [[wire]] - The greater the distance from the [[wire]] the weaker the [[Magnetic Field|magnetic field]].
