    yeah sure. just gonna reply here though

    Back EMF. Now for a motor to rotate, the coil must be supplied with an emf inside a magnetic field (motor effect). The induced emf in a coil opposes the supplied emf within the coil. This happens because the rotating coil in a magnetic field experiences a change in flux thus inducing its own current/emf (Faraday's law- electromagnetic induction). Now this induced current flow in the direction such that its induced magnetic field opposes the field that created it (Lenz's Law). Therefore, the induced emf opposes the supplied emf as the induced magnetic field opposes the change in flux (magnetic field from stator. This is known as Back emf. In a generator, I think the induced emf is the back emf because a generator does not have a supplied emf in the coil.
