A pair of disc magnets used for charging guitar rods/bar magnets. A must have for any pickup builder.
Simply fix each magnet onto something leaving a gap between them slightly wider than the magnets you will pass through the field, then slowly move the uncharged (can be used to recharge degaussed magnets too) magnets between the neo magnets slowly, without touching either one. Repeat several times until the magnets are charged.
2mm thickness, 20mm diameter. Very strong magnets, over 3kg pull force!
