REMANENCE DIRECTION OF Nd₂Fe₁₄B PERMASENT MAGNET AT 77K AS A FUNCTION OF OBLIQUELY APPLIED MAGNETIC FIELD

The remanence direction of Nd₂Fe₁₄B permanent magnet at 77K, initially at saturated remanence along the grain oriented direction, as a function of magnetic field applied along a direction making 70°with the initial remanence direction is calculated neglecting the magnetic interaction between the crystallites. The results are very different from the experimental results obtained by using torque method.
