The first person to conceive of a rotating magnetic field was Walter Baily, who gave a workable demonstration of his battery-operated commutator on June 28, 1879 to the Physical Society of London.

Non-ferrous metals are ejected by magnetic eddy currents in which a rotating magnetic field induces an electric current around the aluminum cans, which in turn creates a magnetic eddy current inside the cans.

It also makes it possible to produce a rotating magnetic field in an electric motor and generate other phase arrangements using transformers ( for instance, a two phase system using a Scott-T transformer ).

:" Fields and waves " was far from my strong point in school, but altering the current flow in a set of coils can create a rotating magnetic field, as was established by Nikola Tesla.

As in a synchronous motor, the stator of the machine is connected to a three-phase supply of voltage Vs ( assumed to be constant ), and this creates a rotating magnetic field within the machine.

Nearly identical to Baily s apparatus, French electrical engineer Marcel Deprez in 1880 published a paper that identified the rotating magnetic field principle and that of a two-phase AC system of currents to produce it.

An AC motor has two parts : a stationary stator having coils supplied with AC to produce a rotating magnetic field, and a rotor attached to the output shaft that is given a torque by the rotating field.

These rotating magnetic fields interact with the magnetic fields of the magnets ( permanent or electromagnets ) in the stationary part of the motor ( stator ) to create a force on the armature which causes it to rotate.
