FIELD: electricity. ^ SUBSTANCE: projections of such magnetisation vectors at flat faces of ferromagnetic toroids are tangent to the specified circumferences. The method to magnetise a ferromagnetic toroid is based on placement of a ferromagnetic toroid into a solenoid, the axis of which is matched with its axis of symmetry, and sending a unidirectional current pulse, the value of which corresponds to magnetic saturation of a ferromagnetic toroid, through a solenoid. An inductance coil is wound onto a ferromagnetic toroid, which is serially connected with a solenoid and a source of a magnetisation current pulse until the ferromagnetic toroid material is saturated, and is shunted with a variable resistor. Afterwards the winding is removed. ^ EFFECT: provision of control with simple means over the ratio of magnetic field intensities developed in the solenoid and the coil wound on the ferromagnetic toroid, which makes it possible to efficiently vary the inclination of the magnetic induction vectors, outgoing from a face of the magnetised ferromagnetic toroid, relative to vertical lines to this face. ^ 1 dwg |
