<p>Two bodies are provided which consist wholly or in part of permanent magnetic or magnetisable material, each body in magnetised condition having one or more polar planes. With at least one of the bodies a stationary magnetic field is created, under the influence of which, w.r.t. at least one other of the bodies in magnetised condition, locally a force of magnetic origin is exerted. The vectorial resultant of this force makes an angle unequal to zero degrees with the normal to the polar plane at the location of the other body. As a result of this, the bodies mutually mve in substance along each others polar planes. Pref. a superconducting electromagnet is used.</p> |
