A metal rod of length l moves translationally with speed v in a uniform magnetic field with magnetic induction B. Determine the EMF of induction in the rod if the vectors of induction B and velocity v are perpendicular to the rod, and the angle between them is equal to a.

έ induction is determined by the formula έ = lBv (if the vectors В V l- are perpendicular, where l-vector coincides with the conductor)
Since the vectors of induction B and velocity v are perpendicular to the rod, and the angle between them is equal to α. So the induction emf will be determined by the formula έ = lBv * sin (α).
