B-H Curve for Permanent Magnets

B-H Curve for Permanent Magnets What is a B-H curve first of all? B is the nomenclature for magnetic flux density (induction) and H is magnetic field strength; a B-H curve plots out the relationship between them for a particular ferromagnetic material. The changes in magnetic flux density is dependent on the magnetic field strength. [...]

Permanent Magnet Stability

Permanent Magnet Stability The ability of a permanent magnet to support an external magnetic field results from small magnetic domains “locked” in position by crystal anisotropy within the magnet material. Once established by initial magnetization, these positions are held until acted upon by forces exceeding those that lock the domains. The energy required to disturb [...]

Segment Magnet Performance Directly Affects Working Efficiency of Motor

Segment Magnet Performance Directly Affects Working Efficiency of Motor Automobile motor magnetic tile: The two phases of alternating current are respectively fed into two or four sets of motor coil windings to form a rotating magnetic field in the motor. The rotating magnetic field generates an induced current in the rotor of the motor, and [...]
