Coil modeling: question about electric field

I have some problem with multi-turn coil modeling. I use 2d axisymmetric geometry. My model is something like this www.comsol.com/support/knowledgebase/916/ Current distribution is calculated correctly. But my real coil is made of a single wire (coiled in a spiral). And so between cross-sections of wire there is a potential difference. And so there is non-zero Oz component of electric field. In example model there is no Ez component (I suppose this is because 2d axisymmetric coil consists of many separate coils and it isn't influence on magnetic field). But in my model (it has different geometry but i hope that problem is clear) this electric field has a great influence. How can I take it into acoount (in 2d axisymmetric)?
Thank you for your attention!
