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. 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 get injured.
Two of these magnets close together can create an almost unbelievable magnetic field that can be very dangerous.
