Back EMF

Generators convert mechanical energy into electrical energy, whereas motors convert electrical energy into mechanical energy. A motor works by sending a current through a loop of wire located in a magnetic field. As a result, the magnetic field exerts a torque on the loop. This rotates a shaft, extracting mechanical work from the electrical curr...

A motor converts electrical energy to mechanical energy. It consists of a current-carrying coil placed inside a uniform magnetic field.

When a current is passed through a coil, the magnetic field exerts a torque on the loop, rotating the coil inside the magnetic field. The magnetic flux through the rotating coil changes, inducing an emf.<...
