Alternate expression for Maxwell's Equations

  1. Sep 8, 2011 #1
    Hello,

    I'm prepping for a course I'm about to take and on the pre-course syllabus it said I should be able to:

    "Derive the equations for E and H fields in terms of magnetic current source M."

    It's been a long time since I've had an EM course, so I'm naturally lost. How would I go about doing this?

    I don't know what a "magnetic current source" might be. If it's simply magnetization, the Ampere-Maxwell Law reads (in Heaviside-Lorentz units)

    [tex]\vec{\nabla} \times \vec{H} - \frac{1}{c} \frac{\partial \vec{D}}{\partial t} = \vec{j} + \vec{\nabla} \times \vec{M}.[/tex]

    If you have a model with magnetic monopoles, have a look in the usual standard textbooks like Jackson or Schwinger.
