Remarks：
1. The above-mentioned data of magnetic characteristics and physical properties are
given at room temperature.
2．Properties are given at magnetic field, perpendicular to the direction of
compression.
3. The maximum service temperature of magnet is changeable due to the ratio length
and diameter and environmental factors.
4. Temperatures TW are given for demagnitization factor that is corresponding to
(BH)
max point.
