Conventional discussions of Maxwell's equations in free space have for
many years taken a historical approach starting with electrostatics a
nd magnetostatics, and have taught us that the sources of E are electr
ic charge and B, and the sources of B are electric current and E. Howe
ver, a direct dynamic reading of Maxwell's differential equations lead
s unquestionably to the surprisingly different conclusions that the so
urces of E are electric current and curl B, and the single source of B
is curl E. In this dynamic reading of Maxwell's equations, electric f
ield is generated locally by electric current, and fields propagate aw
ay from the current source by the dual mechanisms of curl E generating
B locally and curl B generating E locally.
