Neodymium-iron-boron magnets: This type of rare earth magnet has an extremely high magnetic saturation, good resistance to demagnetisation and the highest value of energy production They are less costly to produce than Sm-Co alloys and hence are now the main rare earth permanent magnet in use today.
Stepwise alternating field demagnetisation of NRM identified a single, stable characteristic remanence component with very well defined directions at both a specimen and structure level.
The neodymium magnetics additionally offer greater resistance to demagnetisation, assuring users of repeatable performance throughout the motor's life.
However, Brunhes normal overprinting of an originally reversed CRM is not always successfully removed by alternating field demagnetisation (the laboratory procedure used for most of the samples discussed here), which implies that the true position of the B/M transition may lie higher in the sections.
It was found that during routine use of 3T MRI machines at angles above 80A[bar], demagnetisation reached an unacceptable level.
But the risk of demagnetisation, less powerful and high cost were the problems with these conventional magnets.
The pilot plant will be divided into two modules: the first shreds the HDD and detects and extracts NdFeB magnets; the second includes demagnetisation, size reduction and screening, and purification by magnetic separation, producing a powder.
A demagnetisation feature is also provided which allows the transformer core to be demagnetised on the completion of testing, thereby eliminating the risk of an abnormally high inrush current when the transformer is returned to service.
