We're surrounded by electromagnetic fields yet are rarely made aware of their existence.
The sound of lightsabers in the Star Wars movies famously used a cathode ray television hum, which sounds a bit like EMF recordings of fluorescent lights. I was reminded of this recently when I met an artist named Corrie who was inspired by these lights.
It reminded me that I'd read it's very simple to create a kind of microphone for recording EMFs by using a magnetic coil like the sort found in motors. It also reminded me that I'd saved a couple of these coils for this purpose and it was as easy as soldering a jack onto the red and black wires, leaving the white one that was for earthing.
The video above uses no processing other than adding the EMF recording to the left channel and leaving the right channel with the recording from the camera's mic.
Since making this recording earlier this week I've incorporated it into my Junto and Naviar projects. I'm looking forward to taking it for a walk down the main street of town and hearing how the EMFs sound, which is an idea promoted by Christina Kubisch.
