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.
