Although it has been proved by Herzenberg that such a system works as a selfexciting dynamo, the steady state of it turns out to be unstable for small disturbances. In some special cases, a paradoxical result that the magnetic field continues its growth in spite of non-rotation of the spheres is obtained by the numerical integration of the nonlinear simultaneous differential equations with the aid of a relay computer. This difficulty is caused by the crudeness of approximation for the electromagnetic coupling between the two spheres. If we improve this point, it seems likely that oscillatory fields and velocities could be found. It is intended to apply this study to investigations of the magneto-hydrodynamic actions which are supposed to be in the earth\u0027s
