COIL SYSTEM FOR A CONTACTLESS MAGNETIC NAVIGATION OF A MAGNETIC BODY IN A WORKING CHAMBER

摘要

A magnetic body is contactlessly displaceable in a working chamber (A) by means of a magnetic coil system (2) consisting of fourteen individually controllable individual coils (3a, 3b; 4a bis 4d; 6a to 6d). In addition, three magnetic field components and five magnetic field gradients are produced. Apart from two front individual coils (3a, 3b), the other, in particular saddle-shaped individual coils (4a bis 4d; 6a bis 6d) of the coil system (2) are arranged on lateral tubular surfaces (MF1, MF2) surrounding the working chamber (A).
