Neodymium (or Neo, NIB, NdFeB or rare earth) magnets are an essential part of most DIY alternative energy generators – e.g. wind turbines, wave power generators etc – since they have ten times the power of conventional magnets and can be glued into place with good quality epoxy glues. Invented in the 1980’s their prices are now dropping and they are becoming easier and easier to find and in ever more shapes and sizes.
