A flange part is formed in a shape whose diameter increases toward an outer diameter side of a center core. The flange part closes a space between an end of a magnetic delivery core on a second side in the axial direction and an end of the center core on the second side in the axial direction. An output member includes a contact part, which is brought into contact with an end of the center core on a first side in the axial direction when a plunger moves toward the second side in the axial direction. When the contact part is brought into contact with the end of the center core on the first side in the axial direction, the plunger defines an axial clearance between the plunger and the flange part.

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.

The present invention is a machine in which the repulsion and attraction forces of moving electromagnets are utilized to power a series of linkages that ultimately turn a crank. The motor is controlled by an external computer system which distributes an electric current among the electromagnets. In order to reverse the polarities of the electromagnets, the direction of the current will be rapidly changing. This polarity reverse causes electromagnets to repel and attract. The magnets then oscillate along two swing arms that once swung because of both polarity attraction and repulsion, activate the linkages.
