Hello,

I am calculating the force fore repelling magnet in the attached configuration. In the first configuration magnet diameters are 4 mm and the distance between magnets is 1,7 mm. I rotate the upper magnets and the magnets are repelling (positive axial force for upper magnets).

When I increase the magnets diameter to 5 mm and keep the rest parameter constant, the magnets at the beginning are attracting instead of repelling (negative axial force for upper magnet.) 

So when the magnets are strong and they are very close, regardless of repelling setting, magnets are attracting. Could you please tell me what is the name of this property and how can I calculate the min distance and magnet diameter in which we don't face this attraction? 

Thank you.
