Calculate the emf when a coil of 100 turns is subjected to a flux rate of 0.3 tesla/sec.(a) 3(b) 30(c) -30(d) -300I got this question in my homework.This interesting question is from Faraday Law, EMF and Lenz Law topic in portion Magnetostics of Electromagnetic Theory |
Answer» CORRECT option is (c) -30 To ELABORATE: The induced emf is given by Vemf = -dλ/dt = -Ndψ/dt. Thus emf will be -100 X 0.3 = -30 units. |
