Voltage calculation in 2D axi-symmetric model

Dear all, I am designing a simple 2D axi-symmetric model of single strand coil by providing current excitation in magnetic field (mf) domain. Here, I am measuring the voltage of the coil and then resistance value. When I sweep the Position of the coil from zero-axis, it will generate different revolved geometry. however, I am unable to find how these voltages vary with the position. it seems there is no relation of these voltage changes.
furthermore, computing its DC resistance value using R = pL/A formula is also very complicated in the 2D-axisymmetric model.
please help me to find the how this variation gives different results???
link of the position sweeping mph file is below

I am also attached the mph file without sweeping below:

Isn't it just that the resistance scales linearly with circumference, and the circumference scales linearly with radius? You get twice the voltage at 4 mm than at 2 mm, and four times when comparing 8 mm to 2 mm. And the 0 mm gives you a weird geometry, when seen axisymmetrical, so skip that.
