This is a N52 Neodymium Magnet that weighs approximately 22 lbs (9.79 kilograms). It is 6 inches length, 6 inches in width and 3 inches in depth. It is coated in nickel (NiPLTD). I have a total of 25 of these magnets. This grade of magnet (N52) is the HIGHEST for any rare-earth magnet. A regular refrigerator magnet has a gauss of 100G. THESE MAGNETS ARE EXTREMELY STRONG!!!!! DO NOT OPEN AROUND ANY IRON OBJECTS!!!!! I’m personally demonstrating the power of one of these magnets. Check out the link below for the costs of a smaller magnet.
