===Meaning===
[[File:DCMotor.png|right|300px|thumb|A typical [[D.C. Motor]].]]
A '''D.C. Motor''' is an electrical [[motor]] which uses an [[electromagnet]] and [[Permanent Magnet|permanent magnets]] to spin an axle.
===About D.C. Motors===
: The '''D.C.''' stands for [[Direct Current]] because the [[motor]] uses a [[Direct Current]] to work which means it can be powered by a [[Electrical Cell|cell]] or [[battery]].
: The '''D.C. Motor''' uses the [[Motor Effect|motor effect]] to cause a rotation of the axle.

| style="height:20px; width:200px; text-align:left;" |In a '''D.C. Motor''' there is one or more coils of [[wire]] in the [[Magnetic Field|magnetic field]]. The [[Electrical Current|current]] through one part of the [[wire]] causes it to move in the opposite direction to the other side of the [[wire]]. This causes the coil to spin.
|}
: The [[force]] that can be applied by the '''motor''' depends upon:
:*The number of coils of [[wire]] - Double the coils, double the [[force]].
:*The [[Magnetic Flux Density|magnetic flux density]] - The greater the strength of [[Magnetic Field|magnetic field]] the greater [[force]] on the [[wire]].
:*The [[Electrical Current|current]] through the coil of [[wire]] - The greater the [[Electrical Current|current]] through the [[wire]], the greater the [[force]] on that [[wire]].

It can be seen that when the coil has made a half rotation the [[Electrical Current|current]] through the coil changes direction so that the the left hand side is always .
