Magnetostatic analysis - Applying voltage on symmetric planes

[Sarikahirpara]

hello all,

I am performing a magnetostatic analysis. It consists of vertical sticks of magnets inside the cylindrical case, there is a air gap between each magnetic stick, I want to apply a voltage difference on two vertical sides of stick but I suppose voltage difference can only be applied on symmetric plane. my geometry is not suitable for symmetry analysis. I have attached model of my magnet arrangement.
pls suggest how can I apply voltage on magnet. is it even possible to use this kind of geometry.

Thank you
