Can the have magnetic NdFeB strong magnet be magnetized again after demagnetization at high temperature? Can the original axial magnetization be changed into radial magnetization? This is a common magnet problem. Xiao Fu has also received many similar problems. Today, I specially edit this article to tell you.
Can magnetically charged NdFeB magnets be demagnetized and then magnetized?
Sure. Nd-Fe-B can be demagnetized after magnetization or re magnetized after demagnetization, but its magnetic properties will decline. The magnetic force of the magnet is not determined by the magnetizing machine, but determined by the sintering and forming of the blank. This involves the problem of rare earth ratio, and the magnetized magnet products are not suitable for further machining.
Can the axially magnetized magnet be radially magnetized by the magnet manufacturer?
This problem has been encountered many times by Xiaobian. The magnetizing direction of sintered NdFeB is determined during the production of raw materials. It is axial magnetization or axial magnetization. Its magnetizing direction cannot be changed. You need to explain the required magnetization direction to the magnet manufacturer.
The above is an introduction on whether it is feasible to change the magnetization method of the magnet. If you have any questions about the magnetization of the magnet, please leave a message online or call our company for consultation.
