A method for calibrating a spatial magnetic field course of a magnetic field system to a predetermined spatial shape of the aid of the method and a balanced magnetic field system

摘要

The present invention relates to a method for calibrating a spatial magnetic field course of a magnetic field system at a predetermined spatial shape, wherein the shape of the magnetic field system within a predetermined region of influence of the magnetic field system is measured, is compared with the predetermined shape, on the basis of the deviations in the shape of the inside of the predetermined active region in a feedback process into account a spatial pattern of correction points of a magnetizable material, for the at least partial compensation of the deviations is calculated and this pattern of a magnetizable material in an additive process to at least one not magnetic support outside of the magnet system is applied and then the at least one carrier with a magnetizable material in the magnetic field system is arranged, so that the shape of the magnetic field system within the prescribed working range is matched to the predetermined shape of the. The present invention also relates to a magnetic field system, comprising a, in a predetermined range of actionn="22" a magnetic field as or a magnetic field generating system, such as a permanent magnet system with at least one permanent magnet, wherein the system with the method according to the invention is balanced.n="23"
