Abstract:
A ferrofluidic, electromagnetic power generator for inducing electromotive force in an electrical coil comprising:a closed elongated housing made of non-magnetic material, said housing having two closed ends; said housing partially filled with ferrofluid that has the ability to conduct magnetic flux; an elongated bobbin made of non-magnetic, non-conductive material, said bobbin having a hollow core center extending its entire length, said housing firmly attached within said hollow core of said bobbin, said bobbin extending at least over portion of housing axial length; a coil wound of insulated electrically conductive wire disposed about said bobbin; said coil has the ability to produce electrical power upon enclosing a variable magnetic flux flow; a magnetic assembly comprising: at least one permanent magnet axially polarized; at least two magnetic elongated frames, said magnetic frames are of magnetic material; one end of each of said magnetic elongated frames firmly attached to each closed end of said housing and other end of each magnetic elongated frames firmly attached to each end of said permanent magnet forming a magnetic circuit extending from said permanent magnet to said first magnetic elongated frame to said first closed end of said housing to said magnetized ferrofluid to said second closed end of said housing to said second magnetic elongated frame to said permanent magnet; variation in the distribution of said magnetized ferrofluid within said housing will cause variation in said magnetic circuit causing induction in said coil and producing electrical power; axis of said permanent magnet and first axis of said magnetic elongated frames coincide; axis of said housing and second axis of said magnetic elongated frames coincide, forming a ferrofluidic, electromagnetic power generator.
