SUMMARY
The discussion centers on calculating the electromotive force (emf) generated in a conducting rod of length l moving at a constant speed v, perpendicular to an infinitely long wire carrying a current I. The emf can be determined using the formula ε = B * l * v, where B is the magnetic field around the wire. The magnetic field B at a distance r from the wire is given by B = (μ₀ * I) / (2 * π * r), where μ₀ is the permeability of free space. Thus, the emf generated between the ends of the rod is ε = (μ₀ * I * l * v) / (2 * π * r).
