On Demagnetizing Factor of Cylindrical Rods

Yûki Shirakawa


Abstract:

The ballistic demagnetizing factor of cylindrical rods of ferromagnetic substances, whose dimension ratio is smaller than 10, was experimentally determined by a new method using the demagnetizing curve of New K.S. Magnet alloy having a large coercive force. The relationship between the demagnetizing factor N and the dimension ratio m may be expressed as follows:

N=5.5(m-0.54)-1.4,    m<10.
