Maxwell's equations using vectors D and H

  1. Aug 15, 2011 #1
    1. The problem statement, all variables and given/known data

    Write Maxwell's equations for electromagnetism in differential form:

    in matter, for a linear material, using the vectors D and H

    3. The attempt at a solution

    div D= ro (Gauss' law)
    div H*mu*mu0=0 gauss' law in magnetism
    curl (D/(epsilon*epsilon0))=-dB/dt(partial derivative) faraday's law
    curl H=j(subscript f)+dD/dt (partial derivative) ampere-maxwell law

    I wanted to check whether they were correct

    That looks pretty close. You can check your answer here at hyperphysics:

    BTW, if you want to write "epsilon*epsilon0", you should write "epsilonR*epsilon0", because epsilon = epsilonR*epsilon0. Or in LaTeX:

    [tex]\epsilon = \epsilon_R * \epsilon_0[/tex]

    .

    sorry, I just realised I don't know what epsilon r and mu r actually are. epsilon 0 and mu0 are the permittivity and permeability in free space aren't they? but what does the r stand for? I have tried looking this up
