Demagnetizer drill attachment

Have things that have picked up a bit of unwanted magnetism? Good news: demagnetizing small things like hand tools without damaging them is relatively easy by applying a rapidly altnernating magnetic field. To assemble, you need six standard 6mmx3mm magnets (the stronger the better). Important: place them around the ring in an ALTERNATING PATTERN (i.e. N,S,N,S,N,S around the circle). One easy way to do this is to place three in a triangle in the same pattern, then flip your magnets to place the
