Caption: This video shows the rotation of microspheres in a vertically changing external magnetic field. The color is switched between on (green) and off states. Both movies, taken at different magnifications, were shot using an optical microscope. They show switching of color of the magnetochromatic microspheres, accomplished by simply changing their orientation with the use of a magnet.
