NdFeB Grade N38H Magnetic Performance Thermal performance Demagnetization curve introduction There are many grades of neodymium magnets. For details, see the performance grade table of sintered neodymium iron boron magnets. Today we mainly introduce the 38H performance grade, including its magnetic performance, thermal performance, and demagnetization curve. I hope it will be helpful to those [...]
What is A Magnet Rotor Made of Magnetic Assemblies Magnetic motor rotor is formed by magnetic steel, metal shaft or metal shell. According to detailed application situation, the rotor magnet can be sintered, molded or injection molded with NdFeB magnet material and Ferrite magnet material with multi-poles magnetic rings. It can be used for the [...]
How to Magnetize and Demagnetize a Permanent Magnet Magnets are items with poles and a magnetic field. This is due to the configuration of its electrons. There are three metals that are naturally magnetic; iron, nickel, and cobalt. These metals allow the electrons to configure in such a way that magnetic fields are created around [...]
N55: King of the Permanent NdFeB Magnet The theoretical (BH)max value of N55 NdFeB magnet is 512kJ/m3(64MGOe), and most of magnet manufacturer can make N52 magnet now. The (BH)max of N52 already achieved 90% of theoretical limit. The question in the mind of many users – is there any grade stronger than N52 magnet? N55 [...]
N55 Magnets The theoretical (BH)max value of NdFeB N55 Magnets is 512kJ/m3(64MGOe). The (BH)max of N52 already achieved 90% of theoretical limit. The question in the mind of many users – is there any grade stronger than N52 magnet? N55 is the most powerful grade available currently for commercial use. N55 magnets are the strongest [...]
Magnetism Magnetic Terminology and Definitions Formerly it was beleived that magnetism represented an independent physical phenomenon. It is a fact, however, that magnetic processes are connected to electric processes, that each electric process is a magnetic one at the same time, and vice versa. For a better understanding of physics related to magnets we have [...]
Magnetic Working Point Magnetic Working point (Magnetic operating point) is a point, where the working line (load line) intersects the magnet's B-H demagnetization curve, and indicates the B and H state of the magnet in the magnetic circuit. Knowing the working point is essentia lasit makes possible to forecast the magnetic flux density Bd that [...]
