Abstract:

The calculation of gap fields in iron magnets by means of equivalent surface poles has been explored by several authors. This work is enlarged and the results compared with the performance of a wide range of commercial magnets. Magnet circuits can also be analyzed by a volume integral of dipoles. This removes the restriction of uniform magnetization and allows the optimum direction of magnetization to be explored. General results are given for iron cylinders, and a number of specific tapered poles are analyzed. The homogeneity of fields in the gaps of magnets is presented in the form of a Taylor series of error coefficients. Author
