The motion of a viscous incompressible conducting fluid near a uniformly rotating sphere in a magnetic field oriented along the axis of rotation was studied. A case of slow rotation where inertial forces are neglected as compared to viscous forces and the Reynolds' magnetic number is small was studied, and the velocities and induced field are found. Foemulas are developed for the delaying moment. In weak fields the delaying moment increases proportionately to the square of the field, whereas in strong fields its dependence is linear. The problem of a slowly rotating sphere in a conducting fluid in a magnetic field was resolved previously by the method of approximations. The previously found solution holds good for the weak fields where the velocity distributon differs only slightly from that without any field. A general solution is derived which holds good for strong magnetic fields. (tr-auth)
