Faraday’s Law of Induction 10.1 Faraday’s Law of Induction The electric fields and magnetic fields considered up to now have been produced by stationary charges and moving charges (currents), respectively. Imposing an electric field on a conductor gives rise to a current which in turn generates a magnetic field. One could

experiments are now referred to as Faraday’s Law of Induction. In general, Faradays Law states that an induced emf (E) along any closed path in a magnetic eld is equal to the rate at which the magnetic ux changes along the surface of the area within the path. Quantitatively, E= d B dt (1) where B is the magnetic ux through the closed path ...

Faradays Law and Lenz’s Law Actually, problems involving induction tend not to be so amenable to a simple \how-to": in general, they vary a lot in terms of what you are asked to nd for the nal answer, and in terms how you are expected to use the induced EMF or current. However, there are some systematic steps you can
