Abstract

The present invention relates to a means for reducing or eliminating a remanent magnetic field around for example a joint that is to be welded. The means is characterized in that it includes a permanent magnet (5) which is displaceably mounted between two yokes (3) of magnetically conducting material. The invention does also include a method for the reduction or elimination of remanent magnetism using the means according to the invention whereby the strength and direction of the magnetic field is measured and that the yokes (3) are brought into contact with the materials (1, 2) having the remanent magnetism whereupon the position of the permanent magnet (5) is adjusted so that the remanent magnetic field completely or partly is eliminated.
