Neodynmium magnets and a high speed camera? It turns out it is, as the kids say, oddly satisfying. I was practicing with some macro shots with the Chronos high speed camera, using LED lighting and filming at around 4000 frames per second. I dropped some hard drive magnets and noticed the magnets behaved very oddly and unpredictably.
