Question

Which among the following is true about Faraday’s law of Induction?

(a) An emf is induced in a conductor when it cuts the magnetic flux

(b) An emf is induced in a conductor when it moves parallel to the magnetic field

(c) An emf is induced in a conductor when it moves perpendicular to the magnetic field

(d) An emf is induced in a conductor when it is just entering a magnetic field

The question was posed to me in unit test.

This key question is from Faraday’s Law of Induction topic in division Electromagnetic Induction of Physics – Class 12

Answer 1

The correct answer is (a) An emf is induced in a conductor when it cuts the magnetic flux

The best I can explain: According to Faraday’s law of electromagnetic induction, an emf is induced in a conductor when it cuts across the flux of a magnetic field. If the two ends of the conductor are connected to an outside circuit, the induced emf causes current to flow in the circuit.
