Expert Answer:

Electric motors involve rotating coils of wire which are driven by the magnetic force exerted by a magnetic field on an electric current. They transform electrical energy into mechanical energy.

1.) An electric current in a magnetic field will experience a force

2.) If the current carrying wires is bent into a loop, when the two sides of the loop which are at right angles to the magnetic field will experience forces in opposite direction.

3.) The pair of forces creates a turning influence or torque to rotate the coil.

4.) Particle motors have several loops on an armeture to provide a more uniform torque.
