Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Induced emf | (i) Rate of change of magnetic flux |
| (b) Lenz's law | (ii) Opposes the change in flux |
| (c) Magnetic flux | (iii) Area and magnetic field |
| (d) Total induced emf | (iv) N times the flux change |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-iii, c-i, d-iv
C
a-iii, b-iv, c-i, d-ii
D
a-iv, b-i, c-ii, d-iii
Correct Answer
Option A
Detailed Explanation
The induced emf is indeed equal to the rate of change of magnetic flux (dΦ/dt), and Lenz's law states that it opposes the change in magnetic flux. The magnetic flux is defined in terms of area and magnetic field, while the total induced emf is calculated as N times the change in flux through the coil.
