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) Rate of change of magnetic flux |
| (b) Magnetic flux unit | (ii) Weber |
| (c) Direction of induced current | (iii) Opposes the change |
| (d) Number of turns effect | (iv) Increases induced emf |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iv, b-iii, c-i, d-ii
a-iii, b-iv, c-ii, d-i
Correct Answer
Detailed Explanation
The induced emf in a coil is directly related to the rate of change of magnetic flux, represented as ε = -dΦ/dt. The unit of magnetic flux is the weber (Wb), and the direction of induced current opposes the change according to Lenz's law. Increasing the number of turns in the coil increases the induced emf, as indicated in the context provided.
