Neodymium magnets are the strongest magnets that are commercially available.  Sometimes they are referred to as Rare Earth, Permanent or NdFeB magnets.  They are an alloy of Neodymium, Iron and Boron (NdFeB).  Unless otherwise noted, these magnets will have a triple plating of Nickel-Copper-Nickel.

This tiny magnet is quite incredible. I used two of them together to suspend a hammer! I tried a single magnet, but the hammer almost hit one of the cats - not a good thing despite what some may think. Using just one I was able to easily hold an insert from The Times. That insert is 8 pages and just under A4 size.

You can use them for science experiments, powerful refrigerator magnets, or who knows. The possibilities are nearly endless. Well, nearly endless for what a magnet can do. After all, a magnet most likely will not stop the conflicts in the world or keep people from having a mullet - but you never know.

Also available in lots of 20 and 200 in the Disc Magnets section in our eBay Shop.  The lots of 20 are priced right to be good value no matter how many you purchase.

Health & Safety

Neodymium magnets are incredibly strong.  It is possible to get a real nasty pinch from two discs as small as D1/2" x 1/8".  Consult your doctor immediately if your child has ingested magnets.  It is also advisable to keep them away from persons wearing electronic medical devices and direct exposure to expectant mothers (better to be safe than sorry).  By all means do not attempt to see if it hurts to put a 1" sphere and a D7/8" x 1" rod magnet on either side of the nose (yes, it did happen and it reportedly really hurts).  Actually he was very lucky they didn't crush his nose - seriously.

Be careful when handling these magnets as they can jump together from fairly long distances.  While it can be entertaining, it can cause this type of magnet to chip if not shatter.  It is not a defect, but an inherent property of the NdFeB alloy.  Neodymium magnets have a typical maximum operating temperature of 80c without losing magnetism.  We do carry a grade (N38SH) which can be subjected to about 176c and can be found in our HiTemp Magnets section.
