Examples of rotor coil
rotor coil
A powder dynamometer is similar to an eddy current dynamometer, but a fine magnetic powder is placed in the air gap between the rotor and the coil.

As each coil is energized in turn, the rotor aligns itself with the magnetic field produced by the energized field winding.
