Hi, I am wondering how i could parameterise the following rectangular cross section of the hollow cylinder in cylindrical co-ordinates. If this surface is better parameterised via a different co-ordinate system then by all means use that system. After I have completed the parameterisation i would then like to know how to sum up the flux of all these rectangles to get the total flux through the inside of the cylinder .My aim is to determine the flux around the inside of the cylinder (if that makes any sense) between the radii a and b. The vector field in question is B= k(x/(x^2+y^2), y/(x^2+y^2),0). Where B is the magnetic field.
I know that the answer to this question is ## \text{flux} = \frac{L\mu_{0}I}{2\pi}ln{\frac{b}{a}} ## and i was able to calculate (and confirm) this via a much more simplified approach to this problem. But i would now like to attempt the more mathematically rigorous way. Thank you.
