Problem with complex value of electromagnetic force

Hi,
I am running a simulation to calculate the force between two conductors carrying AC current. I used MF with simple two circles of copper and surrounding of air. I set current density 200 in z direction and -200 on z direction for the second coil. The magnetic field looks great and as expected. But you can see the force evaluation in the bottom of the picture, it is complex value!
Does it mean it is sinusoidal? Even if, this means that the average force is zero? this is not true because there should be a net repulsive force.
Please help me with this problem, Thank you.

what do u mean by complex value? to generate eddy current should use time dependent study step.
