Remark:
     1. The above-mentioned data of magnetic parameters and physical properties are given at room temperature.
     2. The maximum working temperature of the magnet is changeable due to the length-diameter ratio and environment factors.
     3. The density is 7.4-7.65g/cm, the hardness is Hv600,  and the reversible temperature coefficient is α-0.13~ -0.09%/ºC, β -0.80~ -0.50%/ºC
     * The length-diameter ratio of the above table is 1: 1, the test data is based on Nickel plating.
