Hey Mshankar.85,

I can point you in the general direction.

Current flowing in a conductor produces a magnetic field, but there must first be a potential for current to flow, by definition. In an inductor, the conductors are necessarily in sufficiently close proximity for the field of one loop to be inside the field of the adjacent loops. Any charge flowing through that field will be affected by it. Since the electrons flowing around the surface of a conductor are largely responsible for transmitting the current, and since electrons are negatively charged, they will necessarily be affected (held back somewhat) by that field as they race around to feed the load. So you have to look for a field charge calculation, which I think I remembered from back in either electronics or physics coursework. (but that was over 20 years ago, so memory is foggy there, sorry)

Now as I understand it, by definition a conductor will also conduct through the material, so as soon as the switch energizes the windings, the whole conductor is immediately "at the voltage potential of the circuit". Hence, E (voltage) Leads I (current) in an L (inductive ciruit, i.e. motor or coil). This implies to me that you have to find some equation relating the surface area & resistance (per unit length L, perhaps?) of the conductor to the field effect above.

This is the best I can do, good luck.
