The eddy currents create an opposite mangetic field which pushes the coil up, making it levitate.<br /> <br /> ==Equipment==<br /> * Spinning aluminium disk with the electric motor<br /> * Coil connected with power plug<br /> * Liquid nitrogen<br /> <br /> ==Instructions==<br /> * Dip the coil in the liquid nitrogen<br /> * Start the spinning aluminium disk<br /> * Plug the coil<br /> * Move the coil on top of the spinning disk and watch levitate<br /> <br /> <br /> ==Keywords==<br /> <br /> ==Images &amp; Movies==<br /> {{#widget:YouTube|id=uWSOmshE9NI}}</div>
