On my desk I have a Tobh...and a few spools of magnet wire..

Something tells me this won't end well. I'm seriously considering buying a few extra RDAs for experimentation, and thinking one of them shall become a 510 connected electromagnet. Which got me thinking, if they manage to ban our devices we can always have them marketed as an electromagnetism experimentation kit. Include a little magnet wire, some screws, etc and they can't ban it. It's just a science kit. Our juice could be "cooling drops".

You'll need to do something to limit the current... although since it's going to appear to the battery pretty darn close to a dead short, the heat should burn the varnish of the magnet wire

Oh don't worry, i've got resistors to spare. I just think it'd be cool to be able to screw on a spare atty, pull off the top, and pick up bolts when I'm working on my car. Also...it'd be fun to be able to wipe a hard drive with the push of a button.

 

[DavidOck]

Have to be one strong field to wipe a drive, but yes, a fun thought!

I think I'd put the silicone sleeve from a carto over it, so the iron filings don't stick to the coil...

It only takes 10 feet of 30 gauge magnet wire to make a 1 Ohm coil. Sure, that sounds like a lot, but you could probably stick a wick in it and fit it into an evaporation chamber.
