1.	The value of ∫ H.dL will be(a) J(b) I(c) B(d) HThis question was addressed to me in an interview.The above asked question is from Magnetic Vector Potential topic in portion Magnetostics of Electromagnetic Theory
Answer» Correct choice is (b) I The explanation is: By Stoke’s theorem, ∫ H.dL = ∫ CURL(H).dS and from Ampere’s law, Curl(H) = J. Thus ∫ H.dL = ∫ J.dS which is nothing but CURRENT I.
