In a Beams ultracentrifuge, the rotor is suspended magnetically in a vacuum. Since there is no mechanical connection to the rotor, the only friction is the air resistance due to the few air molecules in the vacuum. If the rotor is spinning with an angular speed of 5.00 x 105 rad/s and the driving force is turned off, its spinning slows down at an angular rate of magnitude 0.400 rad/s. The rotor of the Beams ultracentrifuge is a rod 38.2...
