ATTACHED ELECTROMAGNET TO COERCIVE FORCE METER Russian patent published in 2014 - IPC G01R33/12 

FIELD: measurement equipment.

SUBSTANCE: attached electromagnet to a coercive force meter comprises a U-shaped magnetic conductor, cores 1 of which are connected with a magnetic conducting link 2. In the body of the magnetic conducting link 2 there is a sensitive element 4 fixed by a composite material 3, for instance, a Hall sensor, the axis of sensitivity of which is arranged axially to the magnetic flux of the link. On cores 1 there are magnetisation 5 and demagnetisation 6 coils are installed, connected to elements of the measurement circuit 7. Installation of the sensitive element in the magnetic conducting link with the axis of sensitivity axially to the magnetic flux and application of magnetic conducting composite makes it possible to concentrate and evenly distribute the magnetic flux from the controlled item in the magnetic conducting link.

EFFECT: increased sensitivity of an attached electromagnet, increased accuracy of demagnetisation current measurement, coercive force and mechanical properties of a controlled item.
