If you really need unbelievably powerful magnets, here they are.
Uses include magnetic steering of nuclear particles in accelerators, levitation devices, magnetic beam amplifiers, scrap iron separators, etc.
Beware - you must think ahead when moving these magnets.
If carrying one into another room, carefully plan the route you will be taking. Sensitive instruments like computers & monitors will be affected in an entire room. Loose metallic objects and other magnets may become airborne and fly considerable distances - and at great speed - to attach themselves to this magnet.
If you get caught in between the two, you can be severely injured.
These magnets will crush bones in the blink of an eye.
Two of these magnets close together can create an almost unbelievable magnetic field that can be incredibly dangerous.
Of all the unique items we offer for sale, we consider these items the most dangerous of all. Our normal packing & shipping personnel refuse to package these magnets - our engineers have to do it. This is no joke or exaggeration - and we cannot stress it strongly enough. You must be extremely careful - and know what you're doing with these magnets.
Two Supermagnets can very easily get out of control, crush fingers and instantly break ribs or even your arm if opposing poles fly at each other.
A small child recently lost his hand when his father left two # 31 supermagnets unattended. The child picked one up and when he approached the other magnet on a nearby table, it became airborne and obliterated his small hand.
NEVER ALLOW CHILDREN NEAR ANY OF THESE MAGNETS!
If working with multiple Supermagnets, always handle one magnet at a time, secure it, then proceed to the next magnet.
