MAGNETIC PROFILES OF BONDED MAGNETS AFFECTED BY THE MAGNETIZING FIXTURES

The four-pole magnetic profiles of the bonded magnets can be obtained by using planar and circular magnetizing fixtures with and without iro n backyokes. With the aid of an iron fixture and iron backyoke, the bo nded magnets are easily saturated with a shallow saddle profile in eac h pole. The saturation voltage is about 400 V for a 1600 mu F magnetiz er. From a practical point of view, it is better to use the planar fix ture that to use the circular fixture.
