NEET Physics Motional EMF Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Induced emf in a closed circuit | (i) Opposes the change in magnetic flux |
| (b) Induced emf in an open circuit | (ii) Exists across its ends |
| (c) Moving wire in a magnetic field | (iii) Induces current |
| (d) Polarity of capacitor plates | (iv) Positive with respect to negative plate |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
In a closed circuit, the induced emf opposes the change in magnetic flux (a-i), while in an open circuit, it exists across its ends (b-ii). A moving wire in a magnetic field induces current (c-iii), and the polarity of capacitor plates is positive with respect to the negative plate (d-iv), according to the NCERT context.
