The Minus Sign in Faraday's Law Revisited
O'Sullivan, Colm; Hurley, Donal
Physics Education, v48 n1 p87-89 Jan 2013
By introducing the mathematical concept of orientation, the significance of the minus sign in Faraday's law may be made clear to students with some knowledge of vector calculus. For many students, however, the traditional approach of treating the law as a relationship between positive scalars and of relying on Lenz's law to provide the information on the direction of the induced electromotive force may be a preferable pedagogical practice. (Contains 2 figures and 5 footnotes.)
