The motor effect



When a current flows through a wire, a magnetic field will be produced around the wire.  The interaction between this magnetic field and a second magnetic field (either that produced by permanent magnets or by a second current-carrying conductor) causes a force to be exerted on the wire.  We call this the motor effect.
