FE-2100MD rare earth permanent magnet flux density experimental device Introduction
Entrusted by the user, the NdFeB temperature irreversible loss measuring instrument is designed to meet the data quality assessment of its foreign users. The heating temperature is normal temperature ~200 °C, and the magnetic field range is 0~1T. The design method is actually relatively simple, or the enterprise that currently has the permanent magnet material BH measuring instrument can be completed by using the equipment at hand, saving costs. That is, the heating pole of the electromagnet is used to complete the heating of the magnetic steel (heating of the closed-circuit electromagnet and conduction heating by the clamp), and measuring the magnetic flux at different temperatures with the magnetic flux meter and the standard one-dimensional Helmholtz coil ( Or the change of the magnetic moment) obtains the curve of the thermal magnetic flux density loss, and returns the curve of the reversible magnetic flux density loss after returning to the normal temperature flux change after heating, and obtains the irreversible magnetic flux density loss curve. An electromagnet that can apply a reverse magnetic field can also obtain the diamagnetic curve of the material under high temperature conditions, which can be used to evaluate the range of use of the magnet in the magnetic circuit.
