This takes approximately 15 minutes, creating a charge on the capacitor that could be lethal. The capacitor is then discharged through a 12" length of 30 gauge bare iron wire.</p><p>When the high voltage current flows though high resistance wire, the bonds between iron molecules are shattered, resulting in a loud bang, a shower of sparks, and a cascade of wispy filaments floating through the air.</p><p>Not all of the charge on the capacitor is disharged through the wire, so a shorting bar must be used to release the remaining charge. </p> 121 tag:techtv.mit.edu,:Array/185374220 2007-05-17 09:03:01 -0400 Walter Lewin Videos <p>Video demonstrates impact time courtesy Dr. Peter Dourmashkin, MIT</p><p>Demo 17 from Physics I: Classical Mechanics, Fall 1999</p><p>Full class available on </p><p><a href="http://ocw.mit.edu/OcwWeb/Physics/8-01Physics-IFall1999/CourseHome/" target="_blank">http://ocw.mit.edu/OcwWeb/Physics/8-01Physics-IFall1999/CourseHome/</a></p><p>as of May 2007 <br /></p><p> </p> 125 tag:techtv.mit.edu,:Array/185344280 2008-10-10 14:24:44 -0400 MIT Department of Physics Technical Services Group Two carts are connected together on an air track with a spring. Under bright lights you can see the coupled oscillation of the carts back and forth, but under black lights you can see that the center of mass moves at a constant velocity. 103 tag:techtv.mit.edu,:Array/185319260 2008-07-11 16:51:41 -0400 MIT Department of Physics Technical Services Group <p>An cathode ray tube (CRT) television is connected to a video camera. When a strong magnet is brought close to the television screen, the image becomes warped and discolored.</p><p>While many new televisions use flat screen technology, older CRTs produced images by firing electron guns (one red, one green, one blue) through the television body onto the back of the screen. When a magnet is brought close to the screen, it deflects the paths of the electron beams and distorts the picture. A strong enough magnetic field can even create a hole in the electron beams, causing a black spot on the picture. </p><p>This TV has been subject to many magnet encounters, which has permanently damaged the picture. </p> 96
