The demangetization curves for the nanocrystalline Nd-Fe-B magnets of the stoichiometric composition were calculated by using the finite element technique of micromagnetism. The curve, especially _iH_c become smaller with increase of N. The most small the from a series of the curves along different field directions is closer to that for N=∞. _iH_c increases with increase of L. and are close or some what smaller than that the experimental values should be.
