Magnet Angle Deviation

Magnet Angle Deviation Due to the manufacture tolerances in pressing and machining of the magnets, the geometrical axle and magnetizing axle of the magnet usually are not parallel, but differ from each other with a certain angle. This is called angle deviation. Magnet Angle Deviation HSMAG can guarantee an angle deviation less than [...]

Magnetizing Machine

Magnetizing Machine In magnetizing the magnetic domains inside of a magnet are aligned with the magnetizing field. If the magnetizing field strength is high enough, all the domains will be aligned and the magnet is said to be magnetized to saturation. Magnetizing to saturation is usually recommended as only then are the magnetic properties of [...]

Magnetic Working Point

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 [...]

How grade choice affects performance when the NdFeB magnet is subjected to heat

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 [...]

How a magnet is demagnetised by applying an external magnetic field

For note, the effects of temperature and external demagnetising fields are easiest to calculate on NdFeB magnets that may be demagnetised as a result of such exposure if cgs units are used (Gauss, Tesla, MGOe) as cgs units allow faster production of new BH curves. When a new Intrinsic BH curve for Neodymium has been [...]
