Ch10: Rotational Motion
... A woman stands at the center of a platform. The woman and the platform rotate with an angular speed of 5.00 rad/s. Friction is negligible. Her arms are outstretched, and she is holding a dumbbell in each hand. In this position the total moment of inertia of the rotating system (platform, woman, and ...

Physics: Magnets - John Madejski Academy
... Permanent or Induced Magnets Permanent magnets produce their own magnetic field. Induced magnets are made from magnetic materials (eg. iron, steel, nickel, cobalt). They turn into a magnet when held in a magnetic field. Magnetic materials will always be attracted to a magnet. ...

... Therefore when we arrange the magnets and wires as shown in Figure 2, there would be a turning force induced. It forces the wire to rotate at the direction of the arrow in Figure 2. However after a half turn, the turning force would be reversed as shown in Figure 3. So some techniques have to be use ...
