Magnetic field of a wire within a hollow cylinder.

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?
