摘要
For rectangular prisms of dimensions 2a x 2b x 2c with constant material susceptibility X, 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)(1/2) (= 1 similar to 500), a/b(=1 similar to 256), and chi(=0 similar to 10(9)). We introduce an interpolation technique for obtaining N-f,N-m with arbitrary values of c/(ab)(1/2), a/b, and chi.
