The motor effect is the term used when a current carrying wire, in the presence of a magnetic field, experiences a force.
This can be demonstrated easily in a simple school experiment. Place a thin aluminium strip in between two opposing magnets.
Apply an electric current through the aluminium foil.
Using Flemings left hand rule (used when electricity passes through a wire) you can not only see the aluminium strip move but you could have predicted it.
A useful mnemonic to remember the meaning of the motor is to remember.
This motor effect can be used to drive motor
See the definition of motors.
This effect can really be used to drive motors and even motor cars.
