Note:
1. The data above are tested at 20oC.
2. The maximum working temperature for a given magnet could be
less due to the ratio of length and diameter of the magnet, the
structure of its assembly with steel parts and environmental
factors.
3. A strong external adverse magnetic field, shock, vibration
and elctro-magnetic field can result in partial demagnetization.
