These powerful 1" NdFeB cubes are brand new, Licensed NdFeB, Grade 35 material. They come Nickel plated to help prevent chipping and corrosion. Actual field density measured at the surface of one of these magnets is almost 5000 Gauss! Br Max (the maximum field density which can be generated by this material) is 12,100 Gauss (this is considered to be the "Gauss Rating"). One of these magnets, under ideal circumstances can lift around 50 pounds of Iron! - incredible for their size. Although normal ceramic ferrite magnets or AlNiCO magnets of this size would be fairly harmless, NdFeB magnets of this size should be considered "LARGE" and "DANGEROUS" - so please read carefully our warnings below and take them seriously! These are NOT for children and for most applications smaller magnets would be appropriate. NdFeB (Neodymium Iron Boron) magnets These magnets are serious tools and somewhat dangerous if mishandled! Due to their size and dimensions, these magnets are larger than necessary for most applications. These are popular for underwater salvage, and some lifting applications - however, it should be noted, that a heavy, unbalanced load when lifted with magnets can easily break loose! Never use magnets for lifting unless you don't care that the load might unexpectadly break loose! If you really want to lift some heavy weights with magnets like these, get two of them, and stick them to a thick (1/2" or thicker) steel plate, right beside each other, one with North facing out and the other with South. This way, when the assembly comes down on a ferrous item to be lifted, it will "complete" the magnetic circuit and lift a LOT of weight - probably in excess of 100 pounds! Magicians enjoy this particular magnet due to its large size and power. Due to their large size and shape, they have a fairly strong field over some distance! Large magnets are often popular with folks looking for certain minerals, including meteorites! Gold prospectors use large magnets sometimes to filter out the heavy magnetite. These can be very useful in clamping/holding applications. Knife makers, machinests, mechanics, welders...etc - will find them invaluable. It is important to note, the maximum operating tempurature of NdFeB magnets is around 300 deg F, so if using them in a high tempurature application, like welding - it is important to remove the magnet before they get too hot! Again, these are large, and dangerous! Allow two to fly together and they'll probably break. Put two together, and you may never seperate them. (it's all I can physically do to seperate two of these magnets!
