That seems like it wouldn't be good for the disk drive in your lap top....

#(removed comment) You are a racist. If you had any space in your little redneck brain, and actually went to school, you may understand this video. Last time I checked, however, trailer parks don't have electricity, and therefore, no electromagnetism. You fail.

Thats a pretty strong EM field. Is that maglev or just the motors that do that?

I didn't realize that so much magnetic energy flowed through the floor on those things

is that really good for the camera being that close to that? Cool though

Does it work on normal trains/trams?

A magnetic field does not harm electronics (or your testicles). But "static electricity" can harm the hard drive e.g.

#5: suprisingly, many people talk about about magnetic "energy", about "flowing". There's magnetic field, but no energy is lost and there's no "flow" unless there's something interfering with it. Technically, those paperclips are increasing resistance in electromagnets, but the effect is so small it's undetectable.

Also, people mix up mystical energies, EM field and EM waves. Static magnetic field is something totally different from cell phone waves and those are again much different from CRT monitor radiation, gamma rays, etc. With just a little education we could stop the conspiracy theories and panic about electrical appliances.

when it said japanese metro i thought it meant a little car, i'm dissapointed
Cool vid though

#9 thank you Mr. Science Guy!! 8-)

I guess the term radiate would better describe a magnetic field rather than flow, which was the term I used.

But thanks for the clarification!!

Science is Cool!!!!

#3 The motors of the train do that. I think a maglev can do that too. The field won't be strong enough to erase or damage your harddisk.
