Abstract:
A mangle magnetic structure, comprisinga plurality of transversely magnetized parallel cylindrical rods are bundled in a cylindrical shell along a longitudinal axis, each of said cylindrical rods having a direction of magnetization; said cylindrical shell being mounted in a frame defines a hollow core having an interior magnetic field; a conductor is disposed within said core; rotating said plurality of transversely magnetized parallel cylindrical rods together in a given direction, by a means for rotation in said frame, causing said interior magnetic field to rotate in an opposite direction from said given direction; said interior magnetic field producing a current through said conductor; said cylindrical shell providing magnetic lines of force to produce an alternating current axial electromotive force to drive current through said conductor; a cylindrical distribution of magnetization in said plurality of transversely magnetized parallel cylindrical rods when all magnetization vectors are rotated by an angle +&sgr; in the x y plane causing the interior magnetic field to remain constant in magnitude; said interior magnetic field rotates direction by an angle âˆ’&sgr;; said mangle magnetic structure having an angular momentum, when rotating as a whole, derived from the formula: N&it;â€ƒ&it;m&it;â€ƒ&it;rc2+N2&it;â€ƒ&it;m&it;â€ƒ&it;a2where said m is the mass of one of said transversely magnetized parallel cylindrical rods, said rc is the distance to a center of each of said plurality of transversely magnetized parallel cylindrical rods from a center of said cylindrical shell; and said a is the radius of each of said plurality of transversely magnetized parallel cylindrical rods.
