The present invention relates to an electromagnetic generator for generating electricity comprising: an exciter having a first magnetic flux, an electrical conductor operable to generate a second magnetic flux when moved relative to the first magnetic flux, means for causing relative motion between the first magnetic flux and the conductor such that the second magnetic flux generated at the conductor opposes the motion of the first magnetic flux relative to the conductor to simultaneously generate an electromotive force (EMF) and a potential energy that is stored in the second magnetic flux, means for controlling the relative motion between the first magnetic flux and the conductor so that the potential energy stored in the conductor is released by allowing the second magnetic flux to collapse unimpeded by the first magnetic flux, and means for converting the released potential energy to an electromotive force (EMF) across the conductor. The invention further relates to a transformer and to an electric motor.
