Abstract: An electric power generator has a housing having an inner cavity having a center and an inner circumferential surface spaced at a varying radial extent from the center. A magnetic flux generator has a body offset from a point of rotation. The magnetic flux generator is rotatable at the center. The magnetic flux generator has a central passageway for slidably receiving a shaft with a magnet. The magnetic flux generator has a coil mounted about the central passageway in an inductive relation with the magnet. A spring is disposed between the shaft and magnetic flux generator for urging the shaft into contact with the inner circumferential surface whereby as the housing rotates, the magnetic flux generator rotates relative to the housing urging the shaft to travel along the inner circumferential surface causing relative back and forth motion of the shaft through the passageway inducing a voltage in the coil.
