Maxwell Equations I have a simple unique question: Why in the homogeneous Maxwell Equations the E and BField are used and in the inhomogeneous ME the D and HField are used? Please give me an answer as soon as possible!

Maxwell Equations Melo wrote: The E and B fields are force fields. They describe the energymomentum change d(p_0, vec p) of particle of charge q along its path in a given field environment build up by all other charges and currents execept that of the test particle dp_0 = q E . dx d\vec p = q (E dt + dx\times B ) In contradistinction the fields D and B are the local expressions of the field generating charge and current distributions. They are easily understood as jumps of thin charge and current distibutions in a plane (D_right D_left) A s/m^2 = charge density for a charged metal plane in xzplane (H_right H_left) A/m for current density in ydirection The material equations E = 1/eps D, B = mu H are a consequence of the Lorentzinvariance: They hold the velocity of light and its invariance wrt group of Lorentz transformations of fields and spce time coordinates. All in one: H,D take up momentum of a source, E,B deliver momentum at the target. But in the real world this distinction is a bit oversimplified, neglegting the back reaction.  Roland Franzius
