15 Points Two straight conducting rails form a right angle. A conducting bar in contact with the rails starts at the vertex at t = 0 and moves with a constant velocity v = 5.2 m/s along them. A magnetic field with B = 0.35 T is directed out of the page. Calculate: the flux through the triangle formed by the rail at t = 3.0 s the emf around the triangle at that time. The direction of the current flow (Clockwise / Counterclockwise)

15 Points In the diagram, the bar AC has a mass of 50 g. It slides freely on the metal strips 40 cm apart at the edges of the incline. A current I flows through these strips and the bar, as indicated. There is a magnetic field By = 0.20 T directed in the -y direction. How large must I be if the rod is to remain motionless. (Neglect the slight overhang of the rod)
