Match List-I with List-II
| List-I | List-II |
| Law/ Rule | Application |
| (A) Faraday’s law | (I) Determines direction of force on a current carrying wire in a magnetic field |
| (B) Lenz’s law | (II) Obeys principle of energy conservation |
| (C) Fleming’s right-hand rule | (III) Determines direction of induced current |
| (D) Fleming’s left-hand rule | (IV) Electromagnetic induction |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A) - (IV), (B) - (II), (C) - (III), (D) - (I)
(A) Faraday’s law — this matches (IV) Electromagnetic induction. Faraday's law gives the emf induced by a changing magnetic flux.
(B) Lenz’s law — this matches (II) Obeys principle of energy conservation. Lenz's law says the induced current opposes the change that produces it; this is the statement of conservation of energy in induction.
(C) Fleming’s right-hand rule — this matches (III) Determines direction of induced current. The rule gives the direction of the current induced in a conductor moving in a magnetic field.
(D) Fleming’s left-hand rule — this matches (I) Determines direction of force on a current carrying wire in a magnetic field. The thumb, forefinger and middle finger give the force, field and current directions.
Note: Lenz’s law could also be linked with (III), but Faraday’s law fits only (IV) and Fleming’s left-hand rule only (I). Option (2) is the only option with both of these, and it gives B with (II) and C with (III).
