That would definitely work, but the problem would be size =/. I found this, which would be perfect, and the only issue is shipping it to the UK (which is insanely expensive) http://www.coolight.com/product-p/cl-iptc-3v-3-7ft.htm

Haha! Thats a great idea! And an antenna creates an electromagnetic field, so as long as I was able to create an antenna that is senstive to all frequencies, I'd essentially have what I'm looking for... I think. Maybe. Right...? Thanks for your help! I'm going to do some research into antennas!

Ahh, that looks interesting. Will have to have an indepth read of that, thanks! Does that mean I can run an oscillator through an electromagnet (as if the oscillator signal was a current) to make the electromagnet follow that signal? I'll read up more on opamp oscillators now! Another...

Any kind of wave form is acceptable =). The application is to have a bunch of these AC electromagnets with tuned resonate frequencies. The overall intention, is to have about 12 individual electromagnet + battery + resistors (to specify the frequencies) that are fairly small in size. Any idea...

Hello! I'm a long time reader, but this is the first time I've not been able to find the information I've needed already... I have a small electromagnet that needs to have an AC current (it is essential that the electromagnet has a reversing polarity) but the source of power comes from a 6v...
