Magnetic movie

5 minutes

How would the world look if we could see the magnetic fields around us?

Undetectable to the human eye except when accentuated by phenomena such as solar flares and aurora borealis, magnetic fields are nonetheless ubiquitous on the Sun and most of the planets in our solar system, including Earth. Using very low frequency (VLF) audio recordings of crackling electron activity, animated renderings of magnetic fields in motion at NASA’s Space Sciences Laboratories at the University of California, Berkeley, and narrated by magnetic field experts, Magnetic Movie brings a hidden, perpetually kinetic world to life.

Director: Joe Gerhardt, Ruth Jarman
