NEET Physics Motional EMF Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Rod moving in magnetic field (i) Induced emf across ends of the rod (b) Steady state of electrons (ii) Change in magnetic flux (c) Coil rotation in uniform field (iii) Mechanical energy to electrical energy (d) Slip rings and brushes (iv) Connection to external circuit
Choose the correct matching:
a-i, b-ii, c-iii, d-iv
a-iii, b-i, c-ii, d-iv
a-ii, b-iv, c-i, d-iii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
The rod moving in a magnetic field generates an induced emf across its ends due to charge separation (Chunk 2). The steady state of electrons occurs when the induced emf reaches a certain value (Chunk 2). The coil's rotation in the magnetic field converts mechanical energy to electrical energy (Chunk 1). Slip rings and brushes are essential for connecting the coil to the external circuit (Chunk 1).
