Question: Example 28.4: A wire bent into a semicircle of radius r forms a closed circuit with resistance of 1.47 Q and is supplied with 6.0

Example 28.4: A wire bent into a semicircle of radius r forms a closed circuit with resistance of 1.47 Q and is supplied with 6.0 Vdc. The wire lies in the xy plane, and a uniform magnetic eld is directed along the positive yaxis as in Figure. Find the magnitude a) current being supplied, b) and direction of the magnetic force acting on the straight portion of the Wire c) and on the curved portion between 60 and 120. Assurn a 0.75 T magnetic eld and radius = 24 cm. Show the integration step by step and then solve numerically. (20 pts). d3
