An electromagnetic generator comprises one or more flux assembly having at least one coil and at least one magnetic field source separated by a gap. An interference drum has a sidewall at least partially positioned inside the gap and comprising at least one magnetic field permeable zone and at least one magnetic field impermeable zone. The interference drum is movable relative to the at least one coil and to the at least one magnetic field source to alternatively position the at least one magnetic field permeable zone and the at least one magnetic field impermeable zone of the sidewall inside the gap. When the interference drum is moved, magnetic flux is created in the coil, and induces electrical current to flow into the coil. The coil may be connected to an external circuit, such that the electrical current may flow through the external circuit.
