Vector Potential

  1. May 14, 2008 #1
    Hello all. I am hoping someone could lend a hand. I need to determine the vector potential of a long wire. I am given the B-field = ([tex]\mu[/tex]I)/(2[tex]\pi[/tex]r) and I know at some point I will need to use [tex]\nabla[/tex] X A. Thanks in advance.

    What's the equation of [tex] \bar{B} [/tex] in terms of [tex]\bar{A}[/tex]?

    The magnetic field runs in rings around the conductor, so it only an azimuthal component.
    This tells you that the A field generating B will be limited to radial and axial components.
