Electromagnetics Problem

    Electromagnetics Problem....Please Help!

    Please help!

    1) a magnetic field on one side of an infinite plane of uniform surface current K=K*j(hat) is found to be

    B= 1/4* mu(nought)*K*i(hat)

    What is the magnetic field below the plane (accounting for the discontinuity across the plane)
    I think I can use the following formula:

    B(above)-B(below)=mu(nought)(K X n(hat))
    The X here is a cross product.

    Can someone confirm this for me?

    The integral of the magnetic field along a closed path is proportional to the current passing through the closed path. See if you can find suitable symmetry to get what you need.
