The magnetic flux meter is used to measure the magnetic flux value with the Helmholtz coil, and then the magnetic moment value is calculated by the formula, which is often used in magnetic measurement. The formula for measuring the magnetic moment of the magnet with a fluxmeter is as follows: M = K * Ф FE-2100MQ rare earth permanent magnet material quality testing device directly displays the magnetic moment value without the need for customers to calculate again. Compared to the magnetic flux meter is more convenient.
magnetic flux meterCooperate with the Helmholtz coil to measure the magnetic flux value, and then calculate the magnetic moment value by formula is often more commonly used in magnetic measurement work.
Flux meter can be equipped with all kinds of Helmholtz coil or single coil, with liquid crystal display shows the measured magnetic flux size and magnetic field strength of the instrument, it can measure the overall magnetic flux, so as to obtain the value of magnetic flux density and magnetic field strength, Helmholtz Helmholtz coil and fluxmeter for magnet magnetic moment measurement,Measuring Formula of Magnet Magnetic Moment with Flux MeterM = K * Ф where: M refers to the magnetic moment of the magnet, unit: Wb.cm-1.K refers to the Helmholt z coil constant, unit: cm-1. Ф refers to the magnetic flux value, unit: Wb.
magnetic flux meterPrecautions for connecting Helmholtz coil test tooling: Generally, the resistance of Helmholtz coil is relatively large. At this time, the coil resistance participates in the integrating circuit, and the measured magnetic flux Φ1 is lower than the actual value Φ. The actual value Φ =(R coil resistance 10K)* Φ1 /10K (calculated according to 20mWb gear). If other test methods are adopted, the relevant coil internal resistance also needs to be considered.
If you want to directly display the magnetic moment value through the magnetic performance measuring equipment, FE-2100MQ rare earth permanent magnet material quality testing device can test the magnetic flux of the magnet by using a one-dimensional Helmhertz coil, and multiply it by the constant corresponding to the coil to obtain the magnetic moment of the permanent magnet. As an inherent parameter of the permanent magnet material, the magnetic moment can be transmitted to each other. 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. Direct display of magnetic moment values, no need for customers to re-calculate. Compared to the magnetic flux meter is more convenient.
FE-2100MQ rare earth permanent magnet material quality testing device uses a magnetic flux meter to configure a one-dimensional Helmholtz coil, which is mainly used in the magnetic flux measurement of permanent magnet devices under the condition of the coil, multiplied by the coil constant to obtain the magnetic moment of the device, and the materials Br, Hcb and BHmax can be calculated for samples of regular sizes. It has been experimentally verified that the use of a one-dimensional coil to test the axial magnetization of cylindrical, ring and square rare earth permanent magnet samples can be very accurate test of the total material.magnetic momentM (Mz to be exact), using the BH demagnetization curve of the material to be close to a straight line, can accurately calculate the three important parameters Br, Hcb and BHmax of the magnetic properties of the material, thus judging the quality of the material. It is well used in the quality transfer of rare earth permanent magnet materials between material enterprises and material use enterprises. The accuracy and repeatability of magnetic moment test are far better than that of using BH test instruments to test standard samples to transfer data, the high test efficiency can realize the full inspection of all magnetized samples, and find the defects of the device in time, and can ensure the judgment of the magnetic energy product grade of the material.
