Trying to generate magnetic fields and forces on superparamagnetic particles

I have been trying to simulate the force on a micron sized bead at high frequencies with a varying permeability. I am new to comsol and I wanted to start by simulating the magnetic flux so I used the single turn coil module. I found the fields and I calculated the force, but when I wanted to do a time domain analysis to see how the bead would move if it was placed in the field, I got the message that I can not do a time domain analysis with the single-turn coil module.
I am not trying to get the same results using the electric currents module to put 1A of current through my traces. I don't know how to setup the model so that it is controlled by the current rather than the potential difference. Also, when I simulate it, I get a current density, and a potential difference, but absolutely no magnetic flux (0 everywhere).
I havnt been able to find a tutorial that is similar to what I am trying to do, and at this point I am just stuck.
If anyone has any advice on how to get it working, It would really be appreciated.
Thanks!
