Talk:Magnetic field viewing film

"Glow"

It can't "glow" - what energy would be being supplied to make it so? I suspect that it changes colour - but 'glow' implies it's emitting light - which I very much doubt. SteveBaker 06:39, 15 March 2007 (UTC)

I agree wholeheartedly, SteveBaker. But then what do you call this? I mean, is it possible that the magnetic field induces some kind of electroluminescence? Maybe as the magnet approaches the film, the changing flux induces electric current, which gradually dissipates over time once the film stops moving? Clearly energy must be conserved... but that doesn't necessarily mean it isn't glowing. The true test of "glowing" would be to test the film in the dark, and see if it emits light.

I guess that's just the excuse I need to go out and buy some! :-) Of course if I do that and run a proper experiment, it'll be condemned as WP:NOR! <sigh> SteveBaker 15:27, 16 March 2007 (UTC)

Um... claiming that it's glowing is OR of the worst kind: speculations based upon online photos! Here's the manufacturers spec sheet: http://www.magnerite.com/frm_tek.html--Wjbeaty 19:20, 16 March 2007 (UTC)

OK - so it definitely doesn't glow then - that's what I thought. SteveBaker 14:32, 19 March 2007 (UTC)

Re: merge request

To which title?

• Magnetic field viewing film
• Magnet viewing film
• Magnetic viewing film

They all get some google hits. Any comments? Femto 13:09, 19 March 2007 (UTC) (leaning towards the first as it's the most descriptive)

I think the article should be named Magnetic field viewing film - but we should have redirects from the other two names so it doesn't matter all that much. SteveBaker 14:20, 19 March 2007 (UTC)

Merge completed

OK - I've completed the merge and created the two redirects as discussed above. SteveBaker 14:31, 19 March 2007 (UTC)
