I am trying to create a decent magnetic field in an inductor, I come from an electronics background so I am not a master physicist (I might use this knowledge later if I build an radio system or transformer).

I have been studying Maxwell's equations, more specifically Amperes law.

My present understanding of Amperes law is, that a magnetic H field can be created by a constant current density 'J' and/or a varying electric flux density 'D' (partial derivative of 'D').

I am interested in the changing electric flux density as I do not want to use a high current DC source but rather use a high voltage AC source and utilize the inductive reactance to stop high currents flowing and conserve battery life.

Firstly is my understanding correct?

Secondly can anyone help me link the changing potential difference across the inductor to electric flux density?

I have also come to understand by Gauss' law that Electric flux density is created by charge density 'Pv', in which case, does anyone know how to find the charge across two electric potentials?

I realize that this question is a bit ambiguous but that is why I am asking, any help will be appreciated.

Thank you,

Josh.
