What is Magnetic Movie Exhibiting?

I am still having difficulties categorizing the Magnetic Movie into an appropriate category...is this an animation or a documentary of an experiment? Perhaps it is none...

Magnetic Fields surround all the energy sources and the energy transporting wires and etc. The waves in the movie were therefore accurately placed by possible energy sources. However, they have no actual photographs and are not visible to eye. Moving on with this idea, Magnetic Movie is making some natural phenomenon become real. Thus we can make more sense out of what the scientists are talking about. I like the part when one of the scientists use word "hair-ball" and the currents and waves suddenly expand to verify what's being said. Same thing happens when another scientist says "they are all around" and all waves just multiply as if responding to what's being described. In a way waves (thinking they are visible to eye and are real) were responding to the scientists. I believe this movie was a good demonstration on how we use technology and our imagination when the calculations don't provide us a clear picture of what is being discussed. I think using such animation techniques and help us better understand the world around us.
