Magnetic Statue of Liberty

This video was made about a week before the 'Magnetic Thinker' video using the same techniques. Mainly I can model any form that can be saved as a STL file, which used in 3d printing. Each STL object in a scene can have different magnetic alignments.

Optical Stern-Gerlach with a Ferrofluid Cell

submitted by: SirZerp

Using a camera adjacent to an incandescent lamp with a polarizing filter that is supplying light at a 45 degree incidence angle to the ferrofluid cell. Basically, using a bright lamp instead of a camera flash. If you look, you can see the image of the camera reflected in the background. On the other side of the ferrofluid cell is a single rotating magnet, profile view with a north and south poles adjacent to the cell. Only the magnet moves, everything else is fixed in place.
