The magnetic behaviors are important for manufacturers as well as for users when any magnet available is put to use. With this in view, this paper discusses the uniformity of magnetic flux, the magnetic stability, the leakage factor in magnetic circuits, etc. With commercial magnets, the variation rate (σ⁄\barX) of the magnetic flux is about 3 percent. The temperature of tempering or aging affects the temperature coefficient. The degree of stabilization in MT magnet is usually controlled so as to give a flux drop of 7∼10%. The leakage factor in similar serial circuits depends on the reluctance of air gap and the arrangement of permanent magnets.
