Lorentz force computation in AC

I would like to better understand how comsol computes the Lorentz force in AC.
I implemented a magnetic problem (without use the force calculation domain) in AC and I evaluated the Lorentz force contribution along the x axis.
The things are that, in ac, the Lorentz force should have a steady state component and a second component having a frequency that is two time the frequency of the current density/magnetic flux density.
Despite that, comsol provides only one complex number that, in my case, has an amplitude of 5 order of magnitude lower than the average Lorentz force contribution along the same axis.
So, the question is, somebody knows how Comsol treats the computation of the Lorentz force and what is the physical meaning of the number evaluated as Lorentz force contribution and Lorentz force contribution average ?
Thank you
