The magnetohydrodynamic force experienced by spherical iron particles in liquid metal

The paper contains a theoretical investigation of magnetohydrodynamic force experienced by iron particles (well-conducting and ferromagnetic) in well-conducting liquid. The investigation is performed by extending the Leenov and Kolin's theory to take into account the second-order effect. Therefore, the limits of the parent model are taken over to the present results. It is found that the effective conductivity of iron particles in liquid metal, which is important for practical application of the theoretically obtained force, is approximately equal to 1.5·10⁶ S/m. The last result is obtained using a quasi-empirical approach - a comparison of experimental results with the results of the numerical simulation that was performed for various conductivities of the iron particles.
