<p>[QUOTE=&quot;-jeffB, post: 1402797, member: 27832&quot;]Strange but true. One of the Stupid Magnet tricks we used to do in the MRI lab was to drop a dollar bill near the magnet&#039;s bore, and watch it flutter in.</p><p><br /></p><p>The more interesting one, though, was to take the bore cap -- a quarter-inch-thick aluminum plate with a handle -- and wave it near the magnet. It would writhe in your grip like it was alive, but if you held it still, the magnet exerted no force at all on it. It was only the eddy currents, induced by <i>motion</i> through the field, that produced force.</p><p><br /></p><p>I wish I&#039;d been able to try it with an ASE. Maybe I&#039;ll take one along next time I visit.[/QUOTE]</p><p><br /></p>
