256 neodymium magnets 1/8th square. The Alt key is for scale. http://www.kjmagnetics.com/ - site for them http://www.kjmagnetics.com/proddetail.asp?prod=B222G-N52 - the magnets themselves
http://www.gizmag.com/electromagnetic-automobile-suspension-demonstrated/18331/ GM also has shocks that have a special oil in them, that is effected by magnetic fields that changes the viscosity.
they interact with the magnetic lines of flux that runs through the center of our earth through the poles, and back around, side note, when a conductive material breaks the line of flux it generates an electrical current, side side note, if their is an electrical current present, it will generate a magnetic line of flux. Which way the current flows is still open to debate. A more important question is... what came first, the Chicken or the Egg?
