, forces acting on ferromagnetic mineral particles in magnetic field were calculated. The Velocity Verlet algorithm was adopted to simulate the two-dimensional dynamic interaction of two magnetic particles and nine magnetic particles respectively. The results show that the magnetic interaction force and viscous drag are the primary factors affecting the agglomeration of magnetic particles......
the strong interaction among atoms. For either Fe11CrC4(g) or Fe11CrC4(s), the local magnetic moment of Fe at 4c site is larger than that at 8d site in contrary to Cr. The stronger covalent bond of Cr-doped...J. Cent. South Univ.
