Magnetic Movie
4 months ago
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 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?

Any chance of you uploading an HD version?
guys, your work is amazing !!
For those wondering: It's not a 'hoax' or a 'trick'. The video is simply using motion-tracked graphics to help visualize what the human eye (or camera, for that matter) cannot see. The presence of magnetic fields is of course real.
The video is made from computer simulation graphics of magnetic fields superimposed on real video.
I few points:
1. Field lines do not detach either at energies or physical dimensions we live in - the sun is a radically different case because of energy and size.
2. There is no direct way to visual magnetic fields remotely - you have to have some type of charged or electric or magnetic dipole particle within the field and then some type of probe (usually light) which is somehow changed by the field. This is generally true of electric fields as well. The link about to ferrofluid visualization is an example: it's a suspension of magnetite (magnetic dipoles) in oil. Most measurements of the sun's magnetic field involve Zeeman's effect or similar where light spectra are split by the strength of the magnetic field.
3. I'd love to have such remote sensing capabilities - one of the products I make involve electromagnets for engineering and scientific use. Here's how spatial magnetic fields are really measured: take a small magnetic sensor (usually a Hall effect detector). It must be small because the size defines the smallest spatial resolution you can detect. Now automate it's motion (it will get very tedious if you don't) and begin to scan in x, y and z every point within the spatial cube of interest. At each point you need to stop and allow physical settling because the sensor wires will have induces currents from moving through the field which contribute error. This process could take hours if you are looking, say for 1 mm resolution in a 1 m cube (1000^3 points). Once you are finished, take that data and put it into a visualization program. Now you have one static frame - oh, did I mention the field needs to be static and unchanging during the entire scan?
In other words - definitely some fakery used here but it is in some ways representative of reality.
The magnetic field lines on the wires are a little different than I would have expected (at least of there's current runnning)...

A somehow reminding representation of a reality ? Excellent! Most people have no idea of the world they live in. If it has to be the Muppet way...brilliant :)))
