Gifford Scott adjusting the experimental equipment he and two fellow researchers are using to study an extremely small and mysterious twisting force they recently discovered. The phenomenon, reported in a recent issue of The Physical Review, a publication of The American Physical Society, occurs when a warm rod is suspended by a thread in a vertical chamber (center of photo) which is filled with a rarefied cool gas. When a very weak magnetic field is applied parallel to the rod, a slight torque or twisting force results which twists the rod. The experimental equipment is located at the Kettering Magnetics Laboratory, at Oakland University in Rochester, Michigan
