1. The problem statement, all variables and given/known data
If a uniform current with current density s flows around a tube of radius a so it is a surface current, how might I find the magnetic field at some arbitrary position vector r?* 2. Relevant equations BiotSavart? 3. The attempt at a solution I am guessing BiotSavart? Or is there a simpler way since it has nice symmetry?

Your geometry hasn't been described all that well, but why not ampere?
