60x30x6 Mm Powerful Ring NdFeB Magnet
NdFeB magnet, the third generation of rare-earth permanent magnets, is the most powerful and advanced permanent magnets today.
A giant ring magnet (actually closer to a disc with a drill hole) that can be tied with a piece of cord. You can use this to drag your bicycle (and who knows what else) out of the river without a problem. Other uses: Pull your keychain out of a gully or Euro coins out of a pond.
This ring magnet is dangerous and not suitable for children or any kind of "fun use", as it can seriously pinch fingers or lead to any number of injuries.
Neodymium magnets will lose their magnetic properties if heated above 80°C/176°F. Neodymium magnets should never be burned, as burning them will create toxic fumes.
