“The Secret Life of Magnetic Fields”

How do you explain something that’s invisible? Making it visible seems obvious in retrospect, but I’ve never seen any representation of electromagnetic fields remotely like this before:

This is the work of of Ruth Jarman and Joe Gerhardt of Semiconductor Films, commissioned for Britain’s Channel 4. The shapes are based on actual electromagnetic activity:

The secret lives of invisible magnetic fields are revealed as chaotic ever-changing geometries . All action takes place around NASA’s Space Sciences Laboratories, UC Berkeley, to recordings of space scientists describing their discoveries . Actual VLF [very low frequency] audio recordings control the evolution of the fields as they delve into our inaudible surroundings, revealing recurrent ‘whistlers’ produced by fleeting electrons .
