A novel three-dimensional magnetostatic solution based on a modified scalar
potential method has been developed. This method has significant advantage
s over the traditional total scalar, reduced scalar, or vector potential me
thods. The new method was successfully applied to a three-dimensional geome
try of an iron core inductor and a permanent magnet motor. The results obta
ined are in close agreement with those obtained from traditional methods. (
