Abstract
We report an analytical and numerical investigation of the forces and torques on a magnetic point dipole due to the presence of a moving electrically conducting cylinder. The kinematic induction problem is formulated in the quasistatic approximation that is appropriate for low magnetic Reynolds numbers. The motion of the cylinder is either a steady translation along its axis or a steady rotation about it. We find different power laws for the dependence of the force on the distance between dipole and cylinder when it is either small or large compared with the cylinder radius. The power laws for large distances are derived systematically by a long-wave expansion in the axial coordinate. For rotation, the case of a finite cylinder is studied by means of a dipole approximation.
