Simulating the wigglyness of a compass pin

  1. Apr 28, 2014 #1
    Hey guys :)
    I'm working on a little bar magnet and compass simulation.
    You can see my progress here: https://dl.dropboxusercontent.com/u/47501509/fysik/kompasser-och-magnet/index.html

    As the title states I want to make the compasses wiggle a bit like a compass would do naturally.

    What approach do you think I should take?

    Simulate it like a damped spring or pendulum with the equilibrium position being magnetic north.

    Looking into that, thanks!
