From the viewpoint of energy the magnetic coupled force exerted on machining wastes by the nonuniform magnetic field of a permanent magnet has been discussed. The difficult problem that machining wastes attracted by a permanent magnet above the iron base platform has been solved.展开更多

To date, the significant progress has been made in the layered magnetic FM/AFM thin film systems. EB mechanisms have shown substantive research advances. Here some of the new advances are introduced and discussed with the emphasis on the influence of AFlVl layer, the interlayer EB coupling across nonmagnetic spacer, and the interlayer coupling across AFlVl layer, as well as EB related to multiferrioc materials and electrical control.展开更多
