# Alternate expression for Maxwell's Equations

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?

$$\vec{\nabla} \times \vec{H} - \frac{1}{c} \frac{\partial \vec{D}}{\partial t} = \vec{j} + \vec{\nabla} \times \vec{M}.$$
