Apparenlty, scientists at NASA managed to make magnetic fields visible (and very very spectacular):

The secret lives of invisible magnetic fields are revealed as chaotic, ever-changing geometries. All action takes place around NASA's Space Sciences Laboratory, UC Berkeley, to recordings of space scientists describing their discoveries. Actual VLF audio recordings control the evolution of the fields as they delve into our inaudible surroundings, revealing recurrent 'whistlers' produced by fleeting electrons. Are we observing a series of scientific experiments, the universe in flux, or a documentary of a fictional world?
