Faraday's first law: It states that when the magnetic field around a coil changes, an induced emf (and hence induced current) is set up in the coil which stays as long as the change in magnetic flux takes place. This is also known as electromagnetic induction. IInd law: It states that the emf induced in the coil is equals to the rate of change of the magnetic flux.

Thanks a lot.??

G K 7 years, 3 months ago

Well, if you literally ask me, then I would suggest you the whole chapter. But, if you have very less time , then I would suggest you to go for the 1.derivations of prism formula and its minimum deviations. 2.Also, derivations as well as numerical of lens maker's formula. 3.derivations of microscopes and telescopes. 4.Advantage of reflective type over refractive type.
