For the cuspate bi‐cones placed in an axially uniform magnetic field, the surface magnetic charge densities are numerically calculated using the surface magnetic charge simulation method and are illustrated. From the numerical results, the demagnetizing fields and the demagnetization factors [fluximetric (ballistic), magnetometric, and partial demagnetization factors] are obtained and illustrated for various relative permeabilities. Singular lines of demagnetizing force are obtained and illustrated to represent visually the regions in which the demagnetization factors have negative values as the actual problems. © 2001 Scripta Technica, Electr Eng Jpn, 134(3): 1–8, 2001
