Maxwell third equation and its derivation

Statement.(a)  It states that,whenever magnetic flux linked with a circuit changes then induced electromotive force (emf) is set up in the circuit. This induced emf lasts so long as the change in magnetic flux continues.

(b) The magnitude of induced emf is equal to the rate of change of magnetic flux linked with the circuit.

Therefore                               induced emf= – dφm/dt Continue reading “Maxwell third equation and its derivation”

Statement. It states that the total electric flux φE passing through a closed hypothetical surface is equal to 1/ε0 times the net charge enclosed by the surface:

ΦE=∫E.dS=q/ε0

∫D.dS=q

where D=ε0E= Displacement vector Continue reading “Maxwells first and second equations and their derivation”
