Optics of a Ferro Colloidal Fluid #6

Using a lens with a thin layer of sandwiched ferro colloidal fluid to map a magnetic field via optic affects of the field on the magnetic fluid. Blue LED's of the apparatus are spaced at 9 degrees, facing inward directed at the edge of the lens. Notice when the ring magnet (poles facing front/back of the ring) is perpendicular to the fluid plane inside the lens, it then greatly bends the light from each of the leds. I've never seen anything bend light like the magnets in this video. Note -- Most of the time in this video, the magnet is on edge and it is the profile view of the magnetic field we are seeing!
