One aspect of the invention is a generator with at least two commutators mounted on a rotatable shaft. At least two magnetically conductive bars may be mounted in an opposed relationship with at least one of the bars passing through a wire coil. At least two magnets may also be mounted in an opposed relationship. The bars and magnets may be mounted such that they extend between the commutators. In various positions, a magnetic field passes through the two commutators, one of the bars and one of the magnets. The magnet field in the bars changes due to rotation of the shaft and current is induced into the wire coil.
