Multiple magnet transducer with differential magnetic strengths
First Claim
1. A dynamic magnet system, comprising:
- a support structure, anda plurality of magnets oriented in polar opposition for individual movement relative to said support structure, said support structure orienting said magnets for movement in a primarily horizontal direction, at least some of said magnets having mutually different properties, said at least some magnets having different magnetic strengths and ultra low friction ferrofluid bearings between said magnets and said support structure, said magnets having multiple oscillation modes relative to said support structure.

Abstract
A dynamic magnet system, particularly useful for electrical generation, employs multiple magnets in polar opposition to each other for individual movement relative to a support structure. The magnets have a critical angle of displacement from a horizontal static position of less than 1 degree, with at least some of the magnets having mutually different properties. With different magnetic strengths, a greater movement is produced for both magnets in response to movements of the support structure, for particular ranges of magnetic strength ratios, than would be the case with equal magnets. The magnet movement can be translated into an electrical signal to power an operating system. Ultra low friction ferrofluid bearings can be used to establish static coefficients of friction between the magnets and support structure less than 0.02, enabling useful power generation from only slight movements of the support structure.
