These neodymium magnets are currently the strongest type of magnet out there. At 1.5 inch x 0.0625 inch and weighing only 0.5 oz each, these magnets provide incredible pulling strength in a small and lightweight package.
Magnet grade is N52 so it can withstand temperatures up to 80C and has 9.4 lbs of pulling force with a surface gauss of 650G.

Product comes with 10 Neodymium Iron Boron (NdFeB) magnetic alloy magnets. They have a nickel-copper-nickel coating for a smooth, shiny finish that is also corrosion resistant. Use for projects where extra strength in a small size is needed.
The North pole side of each magnet is marked with a letter "N" for easy identification.
