Video: DC Electric Motor

1 rating
The forces on the wire segments of the current loop in an electric motor depends upon the geometry of the loop (relative to the magnetic field) as well as the direction of the current. This animation illustrates those forces and the role of the commutator in switching the current direction so that torque on the loop continues to keep the loop spinning.
