Demagnetizing factors for rectangular prisms

For rectangular prisms of dimensions 2a×2b×2c with constant material susceptibility χ, we have calculated and tabulated the fluxmetric and magnetometric demagnetizing factors N_f and N_m, defined along the 2c dimension as functions of c/(ab)¹2/(=1∼500), a/b(=1∼256), and χ(=0∼10⁹). We introduce an interpolation technique for obtaining N_f,m with arbitrary values of c/(ab)¹2/, a/b, and χ.
