1.	Find the current when the magnetic field intensity is given by 2L and L varies as 0->1.(a) 2(b) 1(c) 0.5(d) 0I have been asked this question by my school teacher while I was bunking the class.This interesting question is from Magnetic Field Density topic in chapter Magnetostics of Electromagnetic Theory
Answer» Right answer is (B) 1 Best explanation: From Ampere law, we GET ∫ H.dL = I. Put H = 2L and L = 0->1. On integrating H with respect to L, the current will be 1A.
