CONCEPT MAP

The unit's own concept map roots the whole chapter at 'Electromagnetic induction and Alternating currents' and branches immediately into its two titled halves. The Electromagnetic induction branch splits further into Faraday's law, Lenz's law, Fleming's right-hand rule, and motional emf (itself branching into the Lorentz-force route and the Faraday's-law route); a separate sub-branch for eddy currents covers their demonstration and applications; another sub-branch, methods of inducing emf, covers changing field, changing area and changing orientation; and a final sub-branch covers self-induction, mutual induction, and the transformer built on mutual induction. …
