I have a problem on calculating the force of permanent magnet

I want to simulate the force on the permanent magnet when a coil geneates magnetic field.
I put a permanent magnet above the spiral coil and induce current on the coil and simulate the force on the permanent magnet.
However, the result is weird. The force is too strong.
In addition, even if I do not induce current on the coil, there is a very big force on the permanent magnet.
Is anybody can explain or help me to do correct simulation?

Thank you
