On Equivalent Expressions for the Faraday's Law of Induction

Revista Brasileira de Ensino de Fisica, 34(1), 1309 (2012) In this paper we give a rigorous proof of the equivalence of some different forms of Faraday's law of induction clarifying some misconceptions on the subject and emphasizing that many derivations of this law appearing in textbooks and papers are only valid under very special circumstances and not satisfactory under a mathematical point of view.
