Which of the following defines the direction of induced emf?
Answer with explanationAnswer: Option B
From Fleming’s Right Hand Rule, there is a definite relation among current or induced e.m.f. (electromotive force), lines of force and motion of the conductor. Fleming’s Right Hand Rule states that—For a moving wire in a magnetic field, if the thumb, the first and second fingers of right hand are extended at right angles to one another, with the first finger representing the direction of magnetic lines of force and the second finger representing the direction of current flow induced by the wire’s motion, the thumb will be pointing in the direction of motion of the wire.
