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 iron backyokes. With the aid of an iron fixture and iron backyoke, the bonded magnets are easily saturated with a shallow saddle profile in each pole. The saturation voltage is about 400 V for a 1600 mu F magnetizer. From a practical point of view, it is better to use the planar fixture that to use the circular fixture.
