Which of the Following Maxwell equation is for nonexistence of isolated magnetic charge?
(a) ∇×E=-\(-\frac{\partial B}{\partial t}\)
(b) ∇×H=J
(c) ∇.D=ρv
(d) ∇.B=0
The question was posed to me in a job interview.
The query is from Radiation topic in section Radiation, Baluns & Polarization of Antennas
