www.hunter.cuny.eduVs = Np Ns and this is easy to remember as the voltage is proportional to the number of turns. Equation (1) is a result of Faraday's law of induction and this is the reason transformers work only with AC. A transformers is called a "voltage step-up transformers" if the secondary voltage Vs is greater than the primary voltage Vp.

www.egr.msu.eduFaraday-Maxwell’s Law of induction. Faraday-Maxwell’s law of induction established the relationship that the emf value versus the number of turns (of a coil) times the rate of change of magnetic flux. The reason for the minus sign is that the direction of the electromotive force direction opposes the change in the flux that produces the ...

web.mit.eduFaraday’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

www.ncert.nic.inmagnetism are now more symmetrical *. Faraday’s law of induction states that there is an induced emf equal to the rate of change of magnetic flux. Now, since the emf between two points 1 and 2 is the work done per unit charge in taking it from 1 to 2, the existence of an emf implies the existence of an electric field.

In addition, we also learned in Chapter 10 that, as a consequence of the Faraday’s law of induction, a changing magnetic field can produce an electric field, according to S d d dt ∫Es⋅ =− ∫∫B⋅dA GG GG v (13.1.2) One might then wonder whether or not the converse could be true, namely, a changing
