Abstract
The magnetic field dragged by a constant convective motion in a conducting fluid was illustrated in the previous paper. When the interaction between magnetic fields and motions is strong, the motions distort magnetic lines of force, while the convection currents are in turn modified by the deformation of magnetic lines of force. We should therefore solve induction equation coupled with equation of motion in order to know the exact behaviors of magnetic lines of force as well as that of fluid streams. The author makes in this paper an attempt at solving the above equations for a model with a pair of convection. It turns out that the pattern of velocity streamlines is markedly distorted while the magnetic flux is deformed only slightly. Time-dependent deformations of both the stream lines and magnetic lines of force are graphically illustrated in series of figures in such a way that they can easily be compared with the results obtained on the assumption of the constant fluid motion.
