Guys, today to say how to detect the intrinsic coercive force of NdFeb magnets, you can refer to the following methods:
Testing instrument:
Pulsed magnetic field magnetometer, vibrating sample magnetometer (VSM) can be used
Detection principle:
When the reverse magnetic field is applied, the remanent magnetization of the magnet is reduced to zero, and the reverse magnetic field strength is the intrinsic coercive force
Detection steps:
First of all, sampling according to certain requirements, such as sampling and testing of each batch of finished products and semi-finished products, the sampling proportion is not less than 20%, and the first batch of products after newly developed products or process changes are 100% fully inspected. Then, prepare the test coil, check whether the input parameters in the computer are correct, and check whether the identification of the loading list is consistent with the material. After that, the sample is placed in a suitable test environment, when the specified temperature and other conditions are reached, the above detection instrument is used to measure, input the geometric size and other parameters of the sample, and finally obtain the test data of the intrinsic coercivity and print records
The above is the content of Xiaobian collation, hope to help you!
