Neodymium magnets also contain Iron and Boron, making them some of the strongest magnets in the world. Magnets of all types create a magnetic field, with both a north and south pole. The magnetic field created by the neodymium magnets is so strong, it will line up to match the magnetic north and south of the earth. It makes a great compass! On a more serious note, the large magnets are so strong that they may even be dangerous if not handled properly. A pair of these magnets will leap into a deadly embrace from over 6 inches apart and may knock chips off themselves from the force of the impact. You’ll be amazed at the super strength of the magnets, but we must warn you to be careful. Any type of magnetic media will be history in the presence of one of these large neodymium magnets. Rectangular Countersunk Mounting Magnet

Unbelievably strong magnet! Watch your fingers if you bring two of them together! These ceramic magnets are a perfect example of how technology is producing new materials with space-age properties. These crystalline, ceramic cobalt-neodymium magnets retain their magnetic strength much longer than normal soft metal magnets and emit their strength to other materials easily. Your students will be totally impressed with the strength of this magnet. Magnet 12 mm in diameter.
