I checked out the K&J web site and came across this;

Remagnetizing Old Magnets
Alnico horseshoe and bar magnets can become demagnetized if dropped, stored without a keeper, or by repelling other magnets. Instead of throwing them out, you can remagnetize them using neodymium magnets. Stroke the north pole of a strong neodymium magnet from the center of the alnico magnet to the south pole end of the horseshoe several times. Then, stroke the south pole of the neodymium magnet from the center of the alnico magnet to the north end of the horseshoe several times. This will recharge the worn out alnico magnet. If you reverse the directions, you'll re-magnetize the horseshoe in the opposite orientation! Check out our D4X0-ND to help identify the poles of your neodymium magnet.
