Neodymium is an extremely soft silvery metallic chemical element having the symbol Nd. Neodymium belongs to the metalloid family of elements and is an uncommon-earth element. It is an extremely hard, silvery white metal which quickly tarnishes when exposed in air and water. The metal has a long history as an alloy for friction and welding. It was used by the Chinese to make firearms which were used by them for many years as military instruments of war.
A very strong magnetic force is produced by neodymium magnet couples when they are placed near one another. This effect is actually due to the fact that the two metals in this particular combination have a total alignment which is much stronger than any single alignment. Neodymium magnets produce the best results when they are placed on either a nickel or a palladium based alloys.
Just to let you know, there are 4 shapes of strong neodymium magnets that are used the most by hobbyists, DIYers, and in manufacturing: These are a neodymium disc magnet, a neodymium ring magnet, neodymium bar magnet & those magnetic balls you have heard so much about.
These types of magnets are not the cheapest to buy and they are not the strongest magnets in the world, although they are in fact the strongest magnets known to man-made materials. They are however unique and they could easily be customized into any shape and size. If you are looking to purchase these rare earth elements in the best form possible then you should definitely consider purchasing them from an authentic supplier who deals in authentic Neodymium magnets. These suppliers can be easily found online and sometimes you can even find them through classified ads. You could also try searching through yellow pages or through listings in some local shops.
