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)

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...
