NEET Physics Motional EMF Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Induced emf formula for a moving conductor (i) Blv (b) Role of the magnetic field in motional emf (ii) Resistance of the conductor (c) Effect of speed on induced emf (iii) Proportional to v (d) Direction of induced current (iv) Lenz's law
Choose the correct matching:
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iv, b-iii, c-ii, d-i
a-iii, b-iv, c-i, d-ii
Correct Answer
Detailed Explanation
The induced emf for a moving conductor is given by the formula Blv, where B is the magnetic field, l is the length of the conductor, and v is the speed. The speed directly influences the induced emf, making it proportional to v, and the direction of the induced current can be determined using Lenz's law.
