Magnetic Damped Pendulum

(Eddy Current Phenomena)


EQUIPMENT
    redball.gif (326 bytes) Large rare Earth magnet on a string pendulum
    redball.gif (326 bytes) Thick Al plate


NARRATIVE
       A magnetic field surrounding a moving magnet will induce eddy currents in the plate. These eddy currents generate a magnetic field which opposes the motion of the magnet.
