Recording EMF

[Mike555]

I have had this idea for to record EMF sounds for some time now but i dont know what kind of circuit i need to be able to do it. I tried to google it but only found stuff about ghost hunting and whatnot, but i simply want to hear the sounds for fun and to be able to hear what kind of sounds different devices make. So what kind of circuit do i need?

EMF sounds, thats a new one on me, what do you mean. I know ELO but not EMF.

EMF ( Electro Motive Force) is measured in Volts with a Voltmeter

I meant to record electro magnetic fields. I'm also interested in recording electro magnetic interference too. But what kind of circuit and parts do i need to make?
