Which, among the following, is the correct expression for alternating

1.	Which, among the following, is the correct expression for alternating emf generated?(a) e=2Blvsin(θ)(b) e=2B^2lvsin(θ)(c) e=Blvsin(θ)(d) e=4Blvsin(θ)The question was posed to me in a job interview.Origin of the question is Generation of an Alternating EMF topic in chapter Alternating Voltage and Current of Basic Electrical Engineering
Answer» Correct answer is (C) e=Blvsin(θ) EASY EXPLANATION: The correct expression for alternating emf generated is e=Blvsin(θ). Where B stands for MAGNETIC field density, l is the length of each of the parallel sides V is the velocity with which the conductor is moved and θ is the angle between the velocity and the length.
