Abstract: Embodiments of an electrical power generation device and methods of generating power are disclosed. One such method comprises creating magnetic flux forces generally transverse to a face of a magnet facing a center of a cylinder, moving a coil of wound conductive material partially through the center opening of the cylinder to produce the electric current and, routing resistive forces generated from the moving coil through an iron core, wherein the first coil is positioned concentrically about a first portion of the core, and further routing the resistive forces around the cylinder.
