Faraday's law is that when the flux in the conductor loop changes, it produces electromotive force in the conductor loop, and obeys to contour integral law , Maxwell Curl Theory is that when the magnetic intensity of a certain point in ether space changes, there produces electric field at that point in ether space, which is the field mutual production theory of "electric field produces magnetic field and magnetic field produces electric field" in the free space which everybody is familiar with, and it obeys differential law , Lorentz magnetic force is that when metal electrons cut magnetic lines, metal electrons forced by move along the conductor to form inductive current, in fact, it doesn't matter whether coil moves or magnet moves, only if there exists relative motion between magnetic field and conductor, metal electrons must cut magnetic lines, which is,"coil stills while magnet moves to the left" and "magnet stills while coil moves to the right" these two situations are the same, which both belong to metal electrons having cut magnetic lines.

Due to the most of particle size are smaller than critical particle diameter Dp at 1 nm CoPt, the effect of superparamagnetism causes the decrease of coercivity. Approximately, the orientation of magnetic easy axis of CoPt thin films is random.

From TEM bright field image, it can be seen that the surface image of CoPt formed discrete islands, and gradually change to continuous film as the CoPt thickness increase. After annealed at 700℃ for 30 minutes, the single domain state is found by the observation of MFM images at 7.5 nm CoPt. At single domain state, the variation of coercivity with particle size agree with the theory of single domain particles.

The results show that, when the electromagnetic field was applicated, the flowability and filling capacity of cupronickel alloy are increased, the surface cracks are eliminated, and the thin-walled cupronickel tube billets with smooth surface can be obtained due to the increase of flowability and filling capacity of cupronickel alloy. The solidification structure of the tube billets is evidently refined, the shape of Ni-rich phase changes from needle-like to bulk and the casting stress declines from 7.2 to 0.32 MPa. With the structure improving, the tensile strength and elongation increase by 5% and 36%, respectively, than those of ordinary continuously cast tube billets.
