FORFARANDE FOR REDUCERING AV MAGNETISKT LECKFELT, SAMT ANORDNING FOR REDUCERING AV MAGNETISKT LECKFELT

摘要

The invention relates to a method and device reducing magnetic stray fields. A current loop (4) is arranged at a distance from a stray field generating means (3) and is supplied with a current having a time function substantially coinciding with the time function of the current in the stray field generating means (3). By means of this arrangement the electrical stray field to a high extent may be neutralized in a region beyond the position of the current conductor (4) regarded in a direction from the stray field generating means (3). The effect on technical equipment and living beings of undesired magnetic stray field is reduced to a substantial extent by means of the invention.
