I have a trouble on calculating electromagnetic force

I want to simulate how much force is induced to the permanent magnet when I use helmholtz coil and put a permanent magnet in the middle of coil.

I simulated and get some results.
However, eventhough I changed current which flows into the helmholtz coil, the force is not changed.
In addition, the result value does not make sense.

I attached my simulation file.
Coudl you help me?
