Electromagnetic field profile around a closed loop

  1. Nov 15, 2014 #1
    Is there a way to determine the profile of the field around a charged closed loop - particularly on the direction normal to the plane of the loop, both front and back?
    For generic values of V, I, B, H, etc., and any dimensions of the loop, any particular formulae possible to obtain?

    Thank you in advance.

    Yes, of course. Expressions for the fields of the circular loop on central axis points can be easily derived. See:
    http://hyperphysics.phy-astr.gsu.edu/hbase/electric/elelin.html
    and
    http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/curloo.html#c1

    General fields at any point in space are way more difficult to determine and they involve elliptic integrals and numerical methods.
