It's known that when a Loop of Conductor with two ends is rotated between opposite poles of a Magnet ( North and South), an emf is induced in the Conductor and if a close path is provided, then current flows through the conductor.

That's pretty much about the EMF, but what is Back Emf in Motors?

Is Back EMF produced by the Stator windings or Rotor windings of the motor? What role does inductance play in Back emf?
