How does a DC motor work?

A DC motor works by convertingelectric powerintomechanical work. This is accomplished by forcing current through a templatecoil pageand Useproducing thisamagnetic fieldthat spins the motor.

ClickThese EasyEdit,brushes thenare found on the end of highlightthe coil wires and make a temporaryelectrical connectionwith the voltage source. In this textmotor, the brushes will make a connection every 180 degrees and current will then flow through the coil wires.
