Motion of a sphere in a conducting liquid under the influence of crossed electric and magnetic fields

V. I. Merkulov

Abstract
The forces that are produced in a conducting liquid under the influence of crossed electric and magnetic multipoles are calculated. The velocity of a sphere under the influence of these forces is calculated by using the experimental resistance coefficient of the sphere motion. The inductive resistance of the moving liquid is calculated assuming that the liquid flows around a sphere without being detached. The efficiency of such a method for the production of thrust, whereby the efficiency increases with increasing dimensions of the sphere, is given. A numerical example for the motion of a sphere in sea water under the influence of electric and magnetic dipoles gives an approximate efficiency of 7%.
