# Rotating Magnetic Field

Rotating Magnetic Field

This Demonstration shows how combining two or three magnetic fluxes varying in space and time can be used to generate a rotating magnetic field inside an electrical device. The horizontal axis gives the angle in degrees measured from a fixed axis and the vertical axis gives the magnitude of the flux. So at a given time, the graphs for , , and give the variation of these fluxes with the angle. The green curve gives the resultant sum of the fluxes.
