Neodymium Magnet Set


These magnets are extremely powerful and produce a magnetic force believed to be the strongest in the world. These magnets are made of an alloy of neodymium, boron and iron. Both magnets produce a field extending over 4". Magnets can detect traces of magnetic substances in items such as a dollar bill. Handle with caution, as separating these fragile magnets is difficult. 14mm outside diameter x 6mm thick. Case included.
