Copper plate influence for permanent magnetic field

Please login with a confirmed email address before reporting spam

There is a small copper plate in permanent magnetic field, which can rotate a little, and due to their eddy currents it can make some influence for initial magnetic field. My main issue is to find that influence, and, as Im newbie in comsol, it become too complicated.

Ive tried to use manual for Magnetically Permeable Sphere in a Static Magnetic Field as this question looks quite similar, but as I tried to made calculations for time dependent (for rotation) the calculation time increased dramatically, and Im not sure that this approach is correct.

So generally the quesion is how to investigate moving metal objects in permanent magnetic field?

Ive will be very grateful for any help with this.
