Reference no: EM13540015

The drawing shows three identical rods (A, B, and C) moving in different planes. A constant magnetic field of magnitude 4.50 T is directed along the +y axis. The length of each rod is L = 1.3 m, and the speeds are the same, vA = vB = vC = 2.9 m/s. For each rod, find the magnitude of the motional emf, and indicate which end (1 or 2) of the rod is positive.
