How does one understand this motional emf by invoking the Lorentz force acting on the free charge carriers of the conductor? Explain.

Solution
The magnetic force `(qvecvxxvecB)`component of the Lorentz force is responsible for motional electromotive force. When a conductor is moved through a magnetic field, the magnetic force tries to push the free electrons through the wire, and this creates the motional EMF.
Concept: Force Between Two Parallel Currents, the Ampere
