Setup Purpose Examine the effects of applying a noncontact magnetic damping force on the dynamic system response. Magnets Magnets can be used to alter the dynamic motion of a body that is either magnetic or can be influenced by a magnetic field. One application of magnetic damping or control is found on roller coasters that use magnets to slow or stop the passenger car. Results A set of stacked magnets will be moved to measureable distances from a conductive cylinder attached to a pendulum. The pendulum will be moved to identical release angles and the transient response will be measured to determine the damping condition for each condition. Theory As a conductive materials passes thru a magnetic field the magnetic field setup by the magnet changes and circular currents called eddy currents are generated in the conductor. These eddy currents then form a magnetic field that opposes the other field resulting in Noncontact damping www.mset.info
