Abstract:
A ferrofluidic, electromagnetic power supply for inducing electromotive force in an electrical coil comprising:a closed housing made of non-magnetic material, said housing partially filled with ferrofluid; at least one coil wound of insulated, electrically conductive wire; said coil has the ability to produce electrical power upon encircling a variable magnetic flux; at least one permanent magnet axially polarized; first surface of said coil is firmly attached to flat surface of said housing assembly; second surface of said coil is firmly attached to first face of said permanent magnet forming a magnetic circuit extending from magnetized ferrofluid through flat surface of said housing through said coil to first face of said polarized permanent magnet to second face of said permanent magnet and back to magnetized ferrofluid forming a ferrofluidic, electromagnetic power supply; variation in the distribution of said ferrofluid within said housing due mechanical dislocations of said housing will cause variations in said magnetic circuit causing induction in said coil producing electrical power.
