Ampere's Law?

  1. Dec 13, 2008 #1
    Is there any way to use Ampere's Law [tex]\oint_{C}\beta d\ell = \mu_{0}I[/tex] to calculate teh magnetic field [tex]\beta[/tex] at a single point if there are no surfaces C such that [tex]\beta[/tex] is constant over the surface's perimeter?

    Thanks

    Raman

    Edit: I mean solve symbolically, no estimation/splitting the integral up into discrete sums

    Ampere's law at a point is the Maxwell equation for curl B~j.
    You then have to solve a differential equation for B.

    what is B~j?

    Depending on the set-up, you may be better off using the Biot-Savart law instead. There may or may not be a way to get an expression for current density J depending on how the question is given.

    Maxwell's equation is (Curl B)=k j. The constant k is different in different systems of units.
    By ~ I meant that (Curl B) was proportional to j.
