1. The problem statement, all variables and given/known data
An infinitely long current carrying wire , with slowly varying current I(t).
Determine the induced E field as a function of distance s from the wire.
3. The attempt at a solution
Quasi static approximation
\oint_{a}^{b}Edl = -\frac{d}{dt} \int_{a}^{b}Bda
Whys is it not
E2{\pi}s= \frac{d(\mu_0)Is}{dt}
I used amperes law to find the B field around the infinite current carrying wire.
