NEET Physics Faraday's Laws Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Induced emf in a coil | (i) Negative sign indicating direction |
| (b) Total induced emf in N turns | (ii) Magnetic flux unit |
| (c) Magnetic flux equation | (iii) Varies with B, A, and angle |
| (d) Magnetic flux unit | (iv) Depends on number of turns |
a-i, b-iv, c-iii, d-ii
a-ii, b-i, c-iv, d-iii
a-iii, b-ii, c-i, d-iv
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
The induced emf in a coil is described by Faraday's law, which includes a negative sign to indicate the direction of induced current, matching (a) with (i). The total induced emf in N turns depends on the number of turns, matching (b) with (iv). The magnetic flux equation varies with the magnetic field strength B, area A, and angle, matching (c) with (iii). The SI unit of magnetic flux is weber, matching (d) with (ii).
