The exchange interaction, but not the spontaneous magnetisation, is strongly influenced by the preparation conditions.
交换交互作用,而不是自发磁化强度,明显地受制备条件的影响。
In a permanent magnet brushless motor, airgap field excited by a 2-pole magnet ring with parallel magnetisation is sinusoidal.
永磁无刷电机中,平行充磁的2极磁环产生的气隙磁场是正弦分布的。
Possessing both magnetisation of solid magnet material and flowability of liquid, it is widely used in engineering fields, such as sealing, lubracation, damping, etc.
