A Simple Algorithm for the Calculation of Hysteresis for Isotropic NdFeB Magnets

Abstract:

The calculation of hysteresis curves with the Stoner-Wohlfarth model is somewhat laborious. For the Nd₂Fe₁₄B phase, the second order magnetocrystalline anisotropy (K₂) constant is relevant, and this case only has been discussed in some studies. In this article, a simple algorithm for the calculation of the Stoner-Wohlfarth model for isotropic NdFeB magnets is described. This algorithm makes easier the modeling of the hysteresis curves of bonded melt-spun NdFeB magnets.
