On electromagnetic induction
arXiv:physics/0008006
Abstract
A general law for electromagnetic induction phenomena is derived from Lorentz force and Maxwell equation connecting electric field and time variation of magnetic field. The derivation provides with a unified mathematical treatment the statement according to which electromagnetic induction is the product of two independent phenomena: time variation of magnetic field and effects of magnetic field on moving charges. The general law deals easily-without ad hoc assumptions-with typical cases usually considered as exceptions to the flux rule and contains the flux rule as a particular case.
