SUMMARY
The discussion clarifies that induced electromotive force (emf) in a straight conductor cannot produce a current when the conductor's velocity is parallel to its length. The induced emf arises from the cross product of the velocity vector and the magnetic field, resulting in a direction that is perpendicular to both. Consequently, while emf is generated, it does not facilitate a current along the wire itself, leading to potential losses due to resistance. This principle is crucial for understanding electromagnetic induction in practical applications.
