NOTES

Note 1. The fundamental electro-magnetic equations of Maxwell for stationary media are:— curl H = 1/c (∂D/∂t + ρν) (1) curl E = -1/c ∂B/∂t (2) div D = ρ B = μH div B = 0 D = kE According to Hertz and Heaviside, these require modification in the case of moving bodies. Now it is known that due to motion alone there is a change in a vector R given by (∂R/∂t) due to motion = u. div R + curl [Ru]
