For the circular cone placed in a uniform axial magnetic field, the surface magnetic charge densities are numerically calculated by the surface magnetic charge simulation method. From the results the surface magnetic charge density distributions and demagnetizing factors ( ballistic, magnetometric and partial demagnetizing factors) are obtained and illustrated for various cases of different aspect ratios (tip angles of cone) and relative permeabilities. Especially, those characteristics around the tips of cones are shown in detail and the behavior at the tips is discussed.
