In the figure below, two straight conducting rails form a right angle. A conducting bar in contact with the rails starts at the vertex at time t = 0 and moves with a constant velocity of 7.53 m/s along them. A magnetic field with B = 0.395 Tis directed out of the page. Calculate (a) the flux through the triangle formed by the rails and bar at t = 2.69 s and (b) the emf around the triangle at that time. (c) If the emf is ɛ = at", where a and n are constants, what is the value of n? *B
