Key words: electromagnetic dimensionless number; electromagnetic casting; electromagnetic field; electromagnetic force; magnetic flux density CLC number: TB97; TG249.7  ... physical properties of different metals, such as electric conductivity, magnetic conductivity and density, make the difference of the electromagnetic force imposed on the surface of the metal......
Magnetic Properties of Ga Doped Nd-Fe-B Sintered Magnets刘金芳,罗河烈,潘树明,聂向富,侯登录摘 要:<正> The magnetic properties of Nd16Fe77B7 and Nd16Fe(61-x)Co16GaxB7(x=0,1,2,4,7)have been measured.Itis found that the remanent magnetization(Br),maximum energy product(BH)maxand the Curie temperature(Tc)decrease with the increase of Ga content.The coercive force(He......
and Engineering, North University of China, Taiyuan 030051, China Received 28 July 2006; accepted 15 September 2006 Abstract: The electromagnetic pump imposes the electromagnetic motive force (Lorentz force) on the liquid metal directly and makes it move along the definite direction by using the function of electric current and magnetic field in the conducting fluid. Compared with the traditional die......
J. Cent. South Univ. (2018) 25: 1295-1305 DOI: https://doi.org/10.1007/s11771-018-3826-4 Hydration film measurement on mica and coal surfaces using atomic force microscopy and interfacial... hydrophobic coal and hydrophilic mica surfaces were measured directly by atomic force microscopy (AFM) based on the bending mode of the nominal constant compliance regime in AFM force curve......
(active magnetic seeds) and reagents with magnetism (magnetic reagents). The magnetic adsorption and magnetic interaction force between particles and particles along with reagents and particles have been promoted. Therefore, the pre-magnetic field can enhance the oriented adsorption of magnetic reagents on the target minerals or the interaction force between magnetic seeds and particles, resultantly......
