1. Problem statement. 2. Known equations Amperes law, biot-savart law 3. Attempt. Just taking steps 1 at a time, I first drew a diagram then I found Jo in terms of I and R, and since it is a non uniform current I know that to find the current I use J = I / A substitute A for 2(pi)rdr, and then integrate and solve for Jo, Am I correct as of this far?
