1.	In good conductors, the electric and magnetic fields will be(a) 45 in phase(b) 45 out of phase(c) 90 in phase(d) 90 out of phaseThis question was posed to me in homework.This is a very interesting question from Displacement and Conduction Current in portion Electric Fields in Material Space of Electromagnetic Theory
Answer» Correct option is (b) 45 out of phase To EXPLAIN: The electric and MAGNETIC FIELDS will be out of phase by 45 in good CONDUCTORS. This is because their intrinsic impedance is given by η = √(ωμ/σ) X (1+j). In polar form we get 45 out of phase.
