UMC Recycle Rare Earth Magnets A Texas-based company recycles neodymium-based magnets to make new ones. Urban Mining Company (UMC), USA, has made a new process for reclaiming magnets containing rare earth metals to produce new, higher performance neodymium iron boron (Nd2Fe14B)-type sintered magnets. The methodology offers a practical way to reuse the minerals that are [...]
Avoid Demagnetising Magnet Demagnetisation is the process whereby a magnet loses all of its magnetic properties. The magnet most prone to demagnetisation is the ferrite magnet due to the alloy it is made of, however all magnets can be demagnetised. To avoid demagnetising your magnet, follow these guidelines: Separating your magnets Make sure you separate [...]
Neodymium Iron Boron Temperature - Temperature Effects on Neodymium Iron Boron (NdFeB magnets) Temperature characteristics of NdFeB grades: The NdFeB magnets are the strongest magnets available. Up to +150 degrees C, they are stronger than the other Rare Earth magnet, SmCo. At around +150 degrees C and above these Neo magnets perform not as strongly [...]
It is possible to demagnetise a Neodymium magnet by applying an external magnetic field in a direction opposite to the direction of magnetisation (DoM) of the NdFeB magnet. The extent of demagnetisation is a function of the total magnetic circuit (and hence the Intrinsic working point), the temperature (and hence the actual BH curve shape [...]
