Surface currents

  1. Feb 29, 2012 #1
    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

    Biot-Savart?

    3. The attempt at a solution

    I am guessing Biot-Savart? Or is there a simpler way since it has nice symmetry?

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

    [tex]\int \mathbf{B} \cdot d\mathbf{l}=\int \mathbf{J} \cdot d\mathbf{a}[/tex]
