The experiment consists of a magnetic stirrer and a marble in a beaker of water. When the magnetic stirrer is turned on a vortex is formed and the marble rolls along the edge of the beaker. If the speed of the marble is known, is it possible to work out the force required to roll the marble at a certain speed. If the force is worked out is it possible to work out the angular momentum of the water. Equations are much appreciated.
