16) Which law/rule states that the magnitude of the induced e.m.f. is directly proportional to the rate of charge of flux linkage ?

Lenz's law

Faraday's first law of electromagnetic induction

Faraday's second law of electromagnetic induction

Fleming's right hand rule

Answer is:

Faraday's second law of electromagnetic induction

Each piece will become a separate magnet having north and south pole

Magnetic property will be destroyed in both the pieces completely

Longer piece only will have magnetic property with north and south pole on either end

One piece will have only north pole and the other piece will have only south pole
