12+-+DC+Motor

A motor uses the **motor effect** - //a current perpendicular to a magnetic field will experience a force// - to produce rotational motion. We use the right hand rule (B - fingers, I - thumb, F - palm) to predict the direction the armature will turn in. A crucial part of a motor is the **split ring (commutator)**, this ensures that the //current changes direction at precisely the right moment// to keep the force turning the armature (coil) in the same direction.
