磁钢的居里等温面,是钢加热时从铁磁性状态向顺磁性状态转变、冷却时则反之的第二级相变面。磁钢感应加热时,居里等温面磁导率的急剧变化及其空间位置的改变将导致感应电流密度和释热源的空间再分布,在一定条件下,这将引起居里相变面不稳定,会随着时间和空间产生波动,断开成独立的区段。 Curie’s magnetic isothermal surface, is heated from the ferromagnetic state to paramagnetic state transition, while cooling the other hand, the second phase transition surface. Magnet induction heating, Curie isothermal surface magnetic permeability of the sharp changes and changes in its spatial position will lead to the induced current density and heat release of space redistribution, under certain conditions, which will cause the Curie phase transition surface instability , Will fluctuate with time and space, broken into independent sections.
