Abstract
In order to compensate external interfering fields inside a superconducting magnet coil, these interfering fields are measured outside of the magnet coil by means of a small induction coil in order to obtain a regulation signal, and, by means of a regulation algorithm, the current through a compensation coil is controlled. The induction coils are effectively decoupled from fluctuations of the stray field of the magnet coil and from vibrations.
