Match List-I with List-II
Choose the correct answer from the options given below: |
(A)-(II), (B)-(III), (C)-(IV), (D)-(I) (A)-(IV), (B)-(II), (C)-(III), (D)-(I) (A)-(IV), (B)-(II), (C)-(I), (D)-(III) (A)-(III), (B)-(II), (C)-(IV), (D)-(I) |
(A)-(IV), (B)-(II), (C)-(III), (D)-(I) |
The correct answer is Option (2) → (A)-(IV), (B)-(II), (C)-(III), (D)-(I)
(A) Faraday's law → (IV) Electromagnetic induction Faraday's law states that the induced emf in a circuit is equal to the rate of change of magnetic flux through it. This directly explains the phenomenon of electromagnetic induction. (B) Lenz's law → (II) Obeys principle of energy conservation Lenz's law states that the direction of induced current is such that it opposes the change in magnetic flux producing it. This ensures that energy is conserved and no violation of conservation of energy occurs. (C) Fleming's right-hand rule → (III) Determines direction of induced current Fleming's right-hand rule (generator rule) gives the direction of induced emf or current when a conductor moves in a magnetic field. (D) Fleming's left-hand rule → (I) Determines direction of force on a current carrying wire in a magnetic field Fleming's left-hand rule (motor rule) is used to find the direction of force acting on a current-carrying conductor placed in a magnetic field. |
