Two straight conducting rails form a right angle where their ends are joined. A conducting bar
in contact with the rails starts at the vertex at time t=0 and moves with a constant velocity of
magnitude 5.20 m/s along them, as shown in the figure. A magnetic field of magnitude B=
0.350 T is directed out of the page.

1)Calculate the magnitude and the direction of emf around the triangle at t=3.00 s.

2)If the resistance of the bar is 1.5
and rails have negligible resistances, draw a graph of
induced current as a function of time.
