A conducting bar placed over the rails starts at vertex at the time t=0 and moves with a constant velocity of 5 m/s along them to the right as shown in the figure. Calculate the emf of the triangle at the time t =4.0 s?

A long copper wire carries a current of I ampere. Calculate the magnetic flux per meter of the wire for a plane surface S inside the wire as shown in Fig. A wire forms a closed circular loop of radius = 1 m and resistance 5 ohm . The circle is centered on a long straight wire; at time t = 0 the current in the long straight wire is 10 rightward. Thereafter
