Permanent Magnet Materials Test System

DX-2012H permanent magnet material magnetic measuring instrument is suitable for measuring the remanence Br, coercive force Hcb, internal magnetism of various ferrites, alnico, neodymium iron boron and samarium cobalt and other permanent magnetic materials. Magnetic performance parameters such as coercive force Hcj and maximum magnetic energy product BHmax, and display B&JH hysteresis loop and demagnetization curve.

The DX-2012MQ rare earth permanent magnet material quality test device uses a fluxmeter to configure a one-dimensional Helmholtz coil, which is mainly used to measure the magnetic flux of the permanent magnet device under the condition of the coil, multiplying the coil constantly to obtain the magnetic moment of the device. For the size of the sample, the materials Br, Hcb, and BHmax can be derived.

The heating pole head of the electromagnet is used to complete the heating of the magnetic steel (separate closed-circuit electromagnet heating and conduction heating through the fixture) and cooperate with the fluxmeter and the standard one-dimensional Helmholtz coil to measure the magnetic flux at different temperatures (or Magnetic moment) change to obtain the thermal magnetic flux density loss curve. 

The DX-2012AM permanent magnet magnetic declination measuring instrument is composed of a three-dimensional Helmholtz coil connected to an independent three-component fluxmeter, which constitutes the hardware test part. The three-component test data is converted by a computer to form a complete set of permanent magnets Material quality testing system.
