Question

As per Faraday's laws of electromagnetic induction, an e.m.f. is induced in a conductor whenever it * a.Cuts magnetic flux b.Lies in a magnetic field c.Moves parallel to the direction of the magnetic field d,Lies perpendicular to the magnetic flux

Answer 1

Faraday's Principle of Electromagnetic Induction states that the emf induced in a loop due by a changing magnetic flux is equal to the rate of change of the magnetic flux threading the loop. The magnetic flux threading a coil of wire can be changed by moving a bar magnet in and out of the coil.

Answer 2

Answer:

option (a) Cuts magnetic flux

Explanation:

• We know that Faraday's first law of electromagnetism clearly states that if a conductor is placed in a varying magnetic field then the emf that is induced will be called an induced emf.
• In situations where the conductor is closed, the current will simply circulate through the circuit which will be called an induced current.
• Faraday's second law of electromagnetic induction states that the magnitude of induced emf (in the coil) will be equal to the rate of change of flux.
• Hence the flux linkages of the coil is calculated as the product of the total number of turns in the coil and the flux associated.
• Therefore as per Faraday's laws of electromagnetic induction, an e.m.f. is induced in a conductor whenever it cuts magnetic flux.
