METHOD OF MAGNETISING FERROMAGNETIC PARALLELEPIPEDS Russian patent published in 2013 - IPC H01F13/00 

FIELD: physics.

SUBSTANCE: invention is intended to magnetise ferromagnetic parallelepipeds, the magnetisation vectors of which are inclined at a certain acute angle relative opposite two faces of the parallelepiped in the direction of longer sides thereof, and said faces are magnetic poles of the ferromagnetic parallelepiped. Disclosed is a method of magnetising ferromagnetic parallelepipeds which is based on placing a ferromagnetic parallelepiped in a solenoid perpendicular to the axis of symmetry thereof and using a saturating magnetic field, the method being characterised by that an inductance coil is wound on the ferromagnetic parallelepiped, the axis of symmetry of said coil being perpendicular to the axis of symmetry of the solenoid; the inductance coil is connected in series with the solenoid to a source of a current pulse for magnetisation of the ferromagnetic parallelepiped to saturation, after which the inductance coil is removed from the ferromagnetic parallelepiped. The ferromagnetic parallelepiped is magnetised, wherein the magnetic induction vectors of the ferromagnetic parallelepiped form a certain acute angle to its two opposite faces, and projections of said vectors on said faces are directed along the longer sides thereof.

EFFECT: method enables to make magnetic systems with a longitudinal inhomogeneous magnetic field, which can be used in magnetic power generation to increase energy efficiency of magnetic generators.
