Abstract

A magnetic body is displaceable in a contact-free manner in a working chamber by the use of a magnetic coil system composed of fourteen individually controllable coils. Three magnetic field components and five magnetic field gradients are produced. Apart from two individual coils in the coil system, the other coils, which may be saddle-shaped coils, are arranged on lateral tubular surfaces surrounding the working chamber.
