1. The problem statement, all variables and given/known data Develop the potential formulation for electrodynamics with magnetic charge. Use the Lorenz Gauge. You will need two scalar potentials (V_e and V_m) and two vector potentials (A_e and A_m). Write Maxwell's equations in terms of the potentials, write the electric and magnetic fields in terms of the potentials, and write the potentials in terms of the charge and current densities. 2. Relevant equations Maxwell's equations for magnetic charge: ∇*E=ρe/ε0 ∇*B=μ0ρm ∇xE=-μ0Jm - dB/dt ∇xB=μ0Je + μ0ε0 dE/dt Lorenz gauge: ∇*A=-μ0ε0 dV/dt Fields in terms of potentials for electric charge: E=-∇V - dA/dt B=∇xA 3. The attempt at a solution I needed to modify Gauss's law of magnetism and Faraday's law to include magnetic charge & current, which is done above in the equations. Next, I'd need to define B and E to satisfy Maxwell's equations. Well, how do I start defining E & B? I cant use the equations given for E and B above, can I? Those are assuming only electric charge right? Most of my classmates are having trouble with this simply because we aren't sure how to start; the idea of a magnetic charge isn't the most intuitive thing for us to wrap our heads around. Any tips on how to begin would be greatly appreciated.
