density is increased. Noted that a magnetic field could make voltage drop. As reported in Refs. [18-19], due to the magnetic hydrodynamic (MHD) effect caused by the Lorentz force acting on moving...J. Cent. South Univ.

and the performance improvement of the levitation system. As we all known, the electromagnetic force is determined solely by the magnetic flux of the levitation clearances [9]. The relationship among the electromagnetic force, levitation gap and flux may be simple and clearer if the feedback of magnetic flux is adopted by the inner loop. In this way, the synthesis of the levitation system......
Study on Thermomagnetic Treatment Fe-25.5Cr-12Co Permanent Magnetic Alloy Zhen Liang1,GAO Run-sheng2,ZHU Dan-yang1,SUN Xue-yin1,SHAO Wen-zhu1,XU Ren-gen1 (1.Technology and Development Centre, Hangzhou Permanent Magnet Group Co., Ltd., Hangzhou, China;2.Department of Materials Science, Harbin Institute of Technology, Harbin, China) 摘要:The magnetic properties and microstructure in a low cobalt......
force is generated by the coupling of the induction current and the magnetic field in the melt. As a result, the energy density of the magnetic field represents pressure acting orthogonally on the magnetic field and towards the centre of the melt[8], so the resulting pressure difference imposed on the melt causes vigorous agitation as soon as the action of the electromagnetic force is felt. Fig.4......
