The measurement principle of the FE-2100MQ permanent magnetic quality measuring instrument is to test the magnetic flux of the magnet by using a one-dimensional Helmhertz coil, multiplied by the constant corresponding to the coil, the magnetic moment of the permanent magnet can be transferred to each other as the inherent parameters of the permanent magnetic material.

FE-2100MQ permanent magnet quality measuring instrumentThe measurement principle

By adopting a one-dimensional helmhertz coilThe magnetic moment of the permanent magnet can be obtained by testing the magnetic flux of the magnet, multiplied by the constant corresponding to the coil, and the magnetic moment can be transferred to each other as an inherent parameter of the permanent magnet material. The FE-2100MQ has its own test software, and can calculate the remanence, coercivity and maximum magnetic energy product of rare earth permanent magnets in cylindrical, circular and square samples, which is convenient for users to determine the energy product grade of magnetic steel.

FE-2100MQ permanent magnet quality measuring instrumentComposition of accessories

　　 FE-2100MQ permanent magnet quality measuring instrumentConsists of the following three parts: measuring the host FE-2100MQ, a one-dimensional Helmholtz coil and a notebook computer (the computer part is optional).

Measuring host FE-2100MQ

This is the main component, which consists of a sophisticated single-chip control system, a low-drift fluxmeter and a high-resolution color screen. The user can directly obtain the measurement result by operating the measurement host. Its front panel is shown in the figure below.

Adj: adjust drift knob Coil: test coil connection interface

Range: range selection Set: set sample shape, parameters

Test: Test Complete Zero: Test Start

Reset: reset key

The rear panel is shown in the figure below.

one-dimensional Helmholtz coil

The coil design is professionally designed and calibrated as a test measuring tool. The uniform area determined is in the range of the round table. The tested coil constant K, DC coil resistance R, etc. are marked on the label. The user needs to write relevant parameters into the FE-2100MQ host when using it.

Terminal Computer

This can be selected by the customer himself, and the test software can be installed on the computer and registered before use. The matching CD has upper computer software, but you need to contact Yongyi Company to issue the registration code when using it. Since the measurement host can operate the entire measurement process and display the measurement results, the computer's role is to count the measurement results, save data and print functions. The computer measurement software interface is shown below.
