Drop a power full neodymium magnet through a vertical cobber tube. When the magnet falls in the gravitation field, through the tube, the acceleration is gone, so that the magnet falls with constant speed. This can bee confirmed by making the experiment with tubes of different length, and observe that the fall time is all most proportional to the length of … text/html 2010-06-02T20:37:01+02:00 Louwrens http://wiki.europhysicsfun.org/sidebar?rev=1275503821&do=diff * Home * About EPF * Contact * People * News * Newsletter * * Map * Regions * * Show Physics 2010 * Show Physics 2009 * Show Physics 2008 * Show Physics 2007 * Nielsen Contest * * Files * * Experiments DB text/html 2010-06-02T20:25:47+02:00 Louwrens http://wiki.europhysicsfun.org/experiments/experimentform?rev=1275503147&do=diff In the form below you can create a new experiment page (or a stub) with the proper sections.
