A pair of exceptionally strong rare earth metal magnets – 28.2 (l) x 19 (dia.) mm each. They are made from NdFeB (Neodymium Iron Boron), providing the highest available magnetic energy of any material. Suitable for a wide variety of applications where a very strong magnet is required. The nickel casing protects the magnets because the material is very brittle.
NOTE: DO NOT allow these 2 magnets to collide with each other as they will shatter and be rendered useless.
