INSTRUMENT FOR MEASURING POWER OF INTERACTION OF FERROMAGNETIC WITH MAGNETIC FIELD Russian patent published in 2009 - IPC G01R33/3873 

FIELD: measuring technology.

SUBSTANCE: invention refers to measuring technology and is designed for measurement of power imparted by magnetic field of symmetrical group of inclined relative to vertical straight line constant magnets (electric magnets) to ferromagnetic body moving along said straight line. Here is disclosed the instrument for measuring power of interaction of ferromagnetic with magnetic field; the instrument consists of a group of symmetrically arranged relative to a vertical line similar direct constant magnets (electric magnets) equally inclined to the said vertical line, of a guiding dielectric pipe, axis of symmetry of which coincides with the said vertical line, of a trial ferromagnetic ball installed into this dielectric pipe till firm contact with an iris diaphragm designed to travel along the dielectric pipe at specified distances, and of piezoelectric shock pick-up electrically connected to a pulse amplifier; also the output of the pulse amplifier is connected to a recorder; notably, angle of incline of lengthwise magnet axes of direct constant magnets changes with transfer of an upper bushing along the dielectric pipe; the upper bushing is equipped with levers hinged to it; other ends of the levers are hinged to the first ends of direct constant magnets (electric magnets); while the second ends of the magnets are pivotally connected to the fixed low bushing secured to the dielectric pipe; they also have similar magnetic polarity.

EFFECT: optimisation of incline angle of lengthwise magnetic axis of constant magnet (electromagnet) relative to trajectory of movement of trial ferromagnetic body, for example of ball shape, by means of measuring power imparted to trial ferromagnetic body with magnetic field of constant magnet (electromagnet).
