In Figure , 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 5.20 m/s along them. A magnetic field with B = 0.350 T is directed out of the page. Calculate (a) the flux through the triangle formed by the rails and bar at t = 3.00 s and
(b) the emf around the triangle at that time.
(c) If the emf is , where a and n are
constants, what is the value of n?
