All About the Strongest Magnet in the World. It's a common concern that a magnet simply won't hold the weight of the project you're trying to complete. It isn't true. Neodymium magnets, also known as neosor rare earth magnets are the most powerful magnets in the world, perfect for any project, large or small.

The rare-earth (lanthanide) elements are metals that are ferromagnetic, meaning that like iron they can be magnetized to become permanent magnets, but their Curie temperatures (the temperature above which their ferromagnetism disappears) are below room temperature, so in pure form their magnetism only appears at low ...

A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd₂Fe₁₄B tetragonal crystalline structure. They are the most widely used type of rare-earth magnet.
