Abstract :
The surface magnetic charge distributions of axially magnetized cylindrical tubes are calculated numerically by the surface magnetic charge simulation method. The obtained results are shown on the outer side surfaces, the inner side surfaces, and the end surfaces for various cases of different aspect ratio, radius ratio, and relative permeability. Using these results, the ballistic demagnetizing factors are obtained
