Select Material Grades for Neodymium Magnets When you are trying to figure out which neodymium magnets to select for your design needs, you would always see the term “grade” or “N rating” from any supplier or manufacturer. Besides a few other criteria, desired material grade must be defined for a neodymium magnet. So, what does [...]
Select Magnet Materials from MPCO Magnets ( Neodymium, NdFeB Magnets, SmCo, Alnico, Ceramic Magnets and others ) When choosing a magnet material to be incorporated into your specific application, their properties need to be identified and compared to correctly evaluate their functional workability and economic feasibility. Design engineers should consider the magnetic requirement, physical requirement, [...]
Magnetic Theory and Design 1. Can you explain the difference between coercive force and intrinsic coercive force? The intrinsic coercive force is the coercivity of a magnet material in a closed circuit configuration. A closed circuit configuration means the magnet does not have any exposed poles. Some examples of a closed circuit configuration are a [...]
Strong Magnet Performance Curve, Demagnetization of Permanent Magnets, Demagnetization curves for a Nd-Fe-B The value of the reverse magnetic field strength required to reduce the magnetic induction to zero when the magnet is magnetized by reverse magnetization in the reverse magnetization is called the magnetic coercive force (Hcb). However, the magnetization of the magnet is [...]
