Ansys Maxwell Coil simulation

Hello everyone. I want to run a very simple simulation on Ansys Maxwell 2D magnetostatic which is cylindrical about Z. The simulation consists of two objects. A magnet and a coil. They are both blocks of a same size. The coil material is copper and magnet material is NdFe30 which has been edited ( I have changed the unit vector to 0 0 1 instead of 1 0 0 in order to create magnetic field aligned with z axis). I have defined vector potential around parts using the region block I drew. And finally I assigned force parameters on both magnet and coil in order to read the magnetic force which is applied to them. My problem is these two forces are not the same at all current values I assign to the coil but they should have same amount according to Newton's third law. What I am doing wrong? I have attached an image of the simulation. Can somebody help me?
