Trying to visualise magnetic fields of a floppy disk.
So far I can see magnetic fields on a magstripe https://www.youtube.com/watch?v=c8nM4Z-hkTw with two polarisers (one of which I rotate in the video, which is contained in a 3D printed holder with gears I made).
I'm awaiting some different polariser film, to see if I can get it to work with a floppy disk.
Trippy! Please do a large-format visual art installation of the results of this... like, project it on a wall or on some other public surface that is... unexpected.
