These 3″ discs are some of the most powerful magnets on the market. Useful for the STRONGEST holding applications. They are freakishly powerful and should only be purchased by users familiar with the proper handling of very large neodymium magnets. Two of these stuck together are impossible to separate by hand.
It is recommended that they be handled with the assistance of at least one other person. As with any rare-earth magnet of this size, they can pinch, crush, or otherwise cause extreme physical harm if they are not handled with the greatest of care and respect. You must read and understand our Neodymium Magnet Safety Page before ordering these magnets. You must also agree to our Terms and Conditions prior to purchasing. THESE ARE VERY DANGEROUS!
