Eddy currents and Torsion Pedulum

  1. Feb 16, 2015 #1
    I am having difficulties writing my damped oscillations lab report. We were asked to write a short essay on eddy currents (creation,direction advantage and disadvantage) and their relationship with torsion pendulums. Also,we have to explain if the copper wheel in the torsion pendulum could be made of plastic?

    Could somebody please explain the relation between Eddy currents and the torsion pendulum?

    I would really appreciate your help.

    Here is a link to a lab exercise that seems to me to explain the role of the eddy current damping in a torsion pendulum quite well.
    There are lots of sources of info on eddy currents.
    Eddy currents have consequences: for this lab, think about Lenz's law, also, think about energy, think about many situations where eddy currents occur.
