neodymium magnets for free - how to - very strong!

In this tutorial video I show you how to salvage super strong neodymium ("rare earth") magnets from old harddrives for free. They are extremely strong and can be used for many different applications, like "electric motors", "perpetuum mobiles", "free energy generators" and other great experiments. Or just use them as a fridge magnet to hold your notes.
This video was shot with my "Samsung Galaxy Note" in HD 1080p.
