ABSTRACT:
The present invention employs a material mass to respond to forces, such as gravity, and the material mass is secured through an intermediate beam, or arm, to a wire coil. The intermediate arm has upper and lower shafts secured thereto, which, when mounted in some form of bearing means, permit the arm, or beam, to rotate, thereby rotating the mass and the wire coil, in response to forces applied to the material mass and forces applied to the wire coil. The coil is formed to pass through a narrow gap between a pair of permanent magnets whereby the coil is subjected to a high density magnetic flux.
