Ampere's law - single or double integral?

  1. May 24, 2008 #1
    Flux = Int B dA

    Why isn't this written as a double integral when we antidifferentiate over an areal?

    Forget about Ampere.

    When you actually go to calculate the flux you can change it to a double integral, if needed: perhaps dA = dxdy.
