    "abstract": "The axiomatic structure of the electromagnetic theory is outlined. We will\nbase classical electrodynamics on (1) electric charge conservation, (2) the\nLorentz force, (3) magnetic flux conservation, and (4) on the Maxwell-Lorentz\nspacetime relations. This yields the Maxwell equations. The consequences will\nbe drawn, inter alia, for the interpretation and the dimension of the electric\nand magnetic fields.",
