Introduction of NCERT Solutions for class 12 Physics Chapter 6 Electromagnetic Induction

So far we have studied only fields that are independent of time. Now we will be concerned with electric and magnetic fields, E(x, t) and B(x, t), that vary with time. The time dependence produces physical phenomena that are not present for static fields-electromagnetic induction and the displacement current. Electromagnetic induction is the production of an electric field by a magnetic field that varies with time. Its discovery is generally credited to Faraday, in 1831; but there is evidence that it was discovered independently in 1 830 by Joseph Henry. Before the experiments of Faraday and Henry it was known, from the work of Oersted in 1820, that a magnetic field is produced by a steady electric current, i.e., a current that is constant in time. Therefore Faraday first attempted to detect an electric field from a strong steady magnetic field.: When the magnetic field changes in the region of a loop of wire, an electric current occurs, as indicated by the deflection of a galvanometer needle. The essential idea of electromagnetic induction is that an electric field is produced by nonzero dB/dt. It is natural to ask whether the situation is symmetric: Does nonzero dE/dt produce a magnetic field? Answers to all these questions will be given in this chapter.From JEE and NEET’s point of view, this chapter is as much important as Rotational motion
