Xenon Flash Tube & Neodymium Magnet

Here's an interesting demonstration of the relationship between electricity and magnetism: a xenon flash tube powered by a laser supply, its plasma stream being manipulated by a neodymium magnet's lines of force.

This is not the way such a flash tube is intended to operate. The engineer estimates that it can be driven in this steady-state fashion for about 20 seconds before it explodes from thermal breakdown, based on his previous experiments with this type of tube. Note that the video is 21 seconds long; he was getting a bit concerned about the continued existence of his hand by the time we flipped the power off, which is why his index finger is cowering in fear by the end of the video. We strongly suggest you do not repeat such an experiment without proper high voltage experience and protective gear.

is that mike oldfield playing in the background?

please tell me, he is my favorite artist and i haven't heard that version of that song

[hp2114b]

Yes it's Mike Oldfield. It's a live version of Tubular Bells from the 'Airborn' live double LP (1980).

Holy shit!!!

okay, this has nothing to do with your experiment, which is but remarkable, but as i watched the video, my stereo was playing the same tune by mike oldfield!

Amazing coincidence...

what was the voltage and frequency of your power supply?

Making Iron man suits are we?

[studiogelb]

but it´s not the magnet whichforms the plasmabeam.

use your finger, you will have a similar result.

or try to insulate the magnet on a stick of wood...

give me some skin

Your tube got hot?
