Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to find out the electric field inside a solenoid if a time varying current is passed through.

However I am stuck with these partial differential equations.

View attachment Electric field solenoid.pdf

Somehow I can't solve them and I think something is wrong.

Because according to equation (13) the electric field will vary with frequency sigma/epsilon.

However when looking at equation (11) the electric field must be varying with the frequency of the magnetic field, which is arbitrary.

I am really confused.

Does anybody know the answer?

thanks
