Vedclass · Answer

(C) The induced electromotive force $(e.m.f.)$ is given by the formula $e = B \cdot l \cdot v \cdot \sin(	heta)$, where $	heta$ is the angle between the velocity vector, the magnetic field vector, and the length of the conductor.When a conductor falls vertically in the north-south direction, it moves parallel to the horizontal component of the Earth's magnetic field lines.Since the conductor is moving parallel to the magnetic field lines, it does not cut the magnetic flux lines.Therefore, the rate of change of magnetic flux is zero, and no induced $e.m.f.$ is generated along the length of the conductor.

$A$ horizontal straight conductor kept in the north-south direction falls under gravity, then
