Through continuous efforts in the past two months, Hunan Yongyi Technology Co., Ltd. has extended the magnetic moment and magnetic declination measurement capability of micro magnetic steel to the measurement of NdFeB samples with a volume of 1mm (see photo). The reproducibility of the measured magnetic declination and magnetic moment meets the requirements of users (the repeatability of the test angle meets 1.0), and successfully supplies relevant inspection equipment for users.
through nearly two months of continuous efforts,Hunan Yongyi Technology Co., Ltd.The micro magnetic steelMagnetic moment and magnetic declination measurementThe ability extends to the measurement of NdFeB samples with a volume of 1mm ³ (see photo), usingFE-2100AM magnetic declination testerThe reproducibility of the measured magnetic declination and magnetic moment meets the user's requirements (the repeatability of the test angle meets ± 1.0 °), and the relevant inspection equipment is successfully supplied to the user.
