Abstract: Thermal flux loss (FL) is one of the important properties in applications of Nd-Fe-B magnets to electrical and electronic devices. FL is expected to occur inhomogeneously in magnets with a complex shape, because it depends on the strength of the local demagnetizing field. Thus, in terms of their applications, we need to predict the inhomogeneous FL from basic magnetic properties measured for a magnet with a simple shape such as a sphere. In this contribution, we propose a method of predicting inhomogeneous initial flux loss, FLint, in a magnet with a complex shape, and compare the predicted values of FLint with the measured ones for a model magnet. Consequently, the predicted and measured distributions agreed with each other. This result suggests that the proposed method can be applied to the prediction of FLint in magnets with a complicated shape used in electrical and electronic devices. ©2006 American Institute of Physics
