Physics-Motional EMF
NEET Physics Motional EMF Match the Following Question
Type: Match the Following-match the column-Easy-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Induced EMF | (i) Mechanical energy conversion |
| (b) Coil rotation | (ii) Change in magnetic flux |
| (c) Lenz's Law | (iii) Opposes the change |
| (d) Slip rings | (iv) Connects to external circuit |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iii, b-iv, c-i, d-ii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
Induced EMF is generated through the conversion of mechanical energy (as in a generator), the coil rotation causes a change in magnetic flux, Lenz's Law states that induced current opposes the change in magnetic flux, and slip rings connect the coil to the external circuit.
