4. The space line is divided into two parts by AD. run . Field free And the uniform magnetic field B in Part II perpendicular to the bottom of the paper Is directed towards ACD is a semicircular conductor loop whose radius. And is the center. The bottom of the loop is at the bottom of the paper. Loop the paper bottom Rotated at a constant angular velocity of the axis passing through the perpendicular center goes. The effective resistance of Lap is R. (1985, 6M)

Space is divided by the line AD into two regions. Region I is field free and the Region II has a unifrom magnetic field B direction into the plane of the paper. ACD is a simicircular conducting loop of radius r with center at O, hte plane of the loop being in the plane of the paper. The loop is now made to rotate with a constant angular velocity omega about an axis passing through O and the perpendicular to the plane of the paper. The effective resistance of the loop is R. (i) obtain an expression for hte magnitude of the induced cureent in the loop. (ii) Show the direction of the current when the loop is entering into the Rigion II. Plot a graph between the induced e.m.f and the time of roation for two periods or rotation.
