Neodymium or Rare Earth Magnets

Hard Neodymium discs, blocks or rings are sold individually and the uses are endless. Neodymium magnets are manufactured from sintered neodymium iron boron. These magnets possess the most powerful magnetic properties in relation to volume and can lift 1000 times its own weight. However these magnets do not possess heat resistant qualities and usually remain stable in temperatures up to 80 C. For higher temperature applications, Rare Earth or Samarium Cobalt is recommended. Also due to the corrosive nature of this material, Neodymium is usually supplied nickel coated. These magnets are usually magnetised through the thickness, and are often used when space is limited and you need a lot of sticking power. Neodymium Magnets or Rare Earth magnets can be used for demonstrating attraction and repulsion, for science, engineering, research and development, education, industry, and magic. However, the larger of these magnets are exceptionally strong and should be used with caution.
