Physics-Motional EMF
NEET Physics Motional EMF Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
Match Column-I with Column-II.
Column-I Column-II (a) Motional EMF (i) Lorentz force on charge carriers (b) Induced emf (ii) Change in magnetic flux (c) Speed of conductor (iii) Constant in rectangular loop (d) Spokes of wheel (iv) Parallel emf across spokes
Choose the correct matching:
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iv, b-iii, c-i, d-ii
D
a-iii, b-iv, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
Motional EMF is explained by the Lorentz force acting on charge carriers (a-i). Induced emf results from a change in magnetic flux (b-ii). The speed of the conductor affects the induced emf, which is constant only in a rectangular loop (c-iii). The spokes of the wheel cause the emf to be parallel across them (d-iv).
