]. On the electromagnetic stirring, Vives[7, 8] firstly brought forward the method of permanent-magnet(PM) rotation. The mechanical rotation of permanent magnet produces rotatory magnetic field and induced current in the liquid metal, thus generates non-touch stir. At the present time, the more increased magnetic flux density and energy product of ferromagnetic permanent-magnet are, the more intensified......
