ABSTRACT:
The present invention relates to an arrangement for reduction of magnetic alternating fields for example in a vehicle or similar which comprises at least one electrical system which comprises at least two elements of which at least one comprises one or more components generating and/or consuming electricity, and which are connected through at least one connecting cable in which flows a current having an alternating current component generating a low frequency magnetic field. The arrangement also comprises at least one detecting element which is arranged to detect the alternating current component, and means for generating a compensating current with the use thereof. The compensating current flows adjacent to the connecting cable in such a way that the low frequency magnetic field is reduced or eliminated.
