Neodymium Magnets are the most powerful permanent magnets commercially available today. They can be over 15 times as powerful as a ceramic (refrigerator) magnets. Neodymium Magnets have a chemical formula of Nd2Fe14B. This means it consists of 2 parts Neodymium, a rare earth element, 14 parts Iron and 1 part Boron. It is often referred to as a “Rare Earth Magnet”, a “Super Magnet”, a “Neo” or a “NIB”, referring to the elements involved (Neodymium Iron Boron).

How can something so small can have powers so strong? Well, that is beyond the scope of this post but intend to come back to that in the coming weeks. In the mean time, suffice to say that I enjoy sharing my enthusiasm with others.

Check out some of these perpetual motion applications of these magnets which demonstrate their potential as a free energy source to get the juices flowing – curtesy of youtube!

There is a small problem in using these as a free energy source however. The First Law of Thermodynamics – i.e. the Law of Conservation of Energy, which essentially stated that the total energy of an isolated system remains constant despite any internal change. This is in effect the arch nemisis to the notion of free energy of any kind. I’m sure that the vast majority of those experimenting with Magnet Motors are aware of this however are brave and stubborn enough to continue to try to find ‘that little as yet unknown factor’ that could possibly make the damn thing work… good luck to you, and if you are one of those people, please do join in with the discussion.
