DEVICE FOR DETERMINATION OF CONTENT OF FERRITE IN MATERIAL Russian patent published in 2004 - IPC

FIELD: measurement technology; testing of magnetic materials.

SUBSTANCE: proposed device has two permanent magnets and conducting circuit in form of inductance coil connected to induction emf recorder. First two opposite poles of magnets are oriented towards each other and are separated by air gap. Two other opposite poles of magnets are interconnected by means of C-shaped magnetic circuit on which conducting circuit is wound. Material under test is placed on rod secured on electric motor axle for rotation at constant angular velocity through air gap between poles of permanent magnets in vertical plane relative to field lines connecting these poles.

EFFECT: enhanced sensitivity and accuracy of measurements.
