List of top Physics Questions on Motional Electromotive Force asked in CUET (UG)

A straight metallic rod of length $L$ is oriented horizontally and dropped vertically downward with a speed $v$ perpendicular to the horizontal component of the Earth's uniform magnetic field $B_H$. The instantaneous motional electromotive force (EMF) induced across the two ends of this rod is:

Figure shows a rectangular conductor PQRS in which the conductor PQ is free to move. The conductor PQ is moved towards the left with a constant velocity V as shown in the figure. Assume that there is no loss of energy due to friction. What will be the magnetic flux linked with the loop PQRS and the motional emf?
