Multiple magnetic flywheel driven by a centrifugal clutch

Abstract: A magnetic flywheel for a manually-driven magneto megohmmeter with step variable voltage comprising a rotor formed by a ring of magnetic material carrying permanent magnets, and a stator, disposed inwardly of the rotor and formed by an assembly of magnetic circuits each having a C-shape with a coil wound around the central portion thereof and with two pole surfaces at the ends. In order to reduce the starting torque, the number of pairs of permanent magnets is one less than the number of magnetic circuits, and the angular distance between the pole surfaces of one magnetic circuit is equal to the angular distance between two adjacent permanent magnets. Also, the arc length of each pole surface of a magnetic circuit is substantially equal to half the angular distance between two adjacent permanent magnets.

Magneto-Optical and Magneto-Dielectric Anisotropy Effects in Magnetic Fluids

Abstract: An overview of the magneto-optical and magneto-dielectric effects in magnetic fluids is presented encompassing experimental results and different phenomenological models used to explain these effects. The role of the different parameters on these effects, are discussed. It is suggested that the field induced-mechanical anisotropy produced by agglomeration and chain formation in magnetic fluids is the main cause for these magneto- optical and magneto-dielectric effects in magnetic fluids. Keywords: Magneto-optics, Magnetic fluids, Faraday rotation, Faraday ellipticity, Transmission, Optical anisotropy, Birefringence, Dichroism, Degree of polarization, Polarization effects, Magneto-dielectric effects, Dielectric anisotropy, Chain formation.

Investigation of Capabilities of Magneto-Cumulative Megagauss Magnetic Field Generation

Abstract: Magnetic flux compression in cylindrically imploded liners allows the generation of the highest magnetic fields exceeding 107 G [1, 2]. However, in some cases when it is necessary to protect the samples against explosion, the magnetic flux compression generators pressing the flux out the generator volume to the load are the most suitable.
