Abstract
The present invention relates to a downhole tool for removing metallic debris from a well bore. The downhole tool includes a plurality of magnets disposed on the tool body. The plurality of magnets are arranged in a bucking arrangement such that repulsing forces are generated between neighboring pairs of the plurality of magnets. The bucking arrangement results in an expanded reach of the magnetic fields of the magnets to enhance the removal of metallic debris.
