Spinning Bacteria (VIDEO) Penn State This video is under embargo. Please login to access this video.

Then the slide was turned over and the particle settled to the bottom of the drop. A spinning magnetic field created by four coils spins the particle. The spinning caused the bacteria to clump together around and under the spinning nickel particle. It also created a depletion ring around the bacteria where few if any bacteria were found. The spinning bacterial cluster and the depletion ring were visible.
