PHY2061 R. D. Field Problems Chapter 33 Page 1 of 6 Chapter 33 Problems Problem 1: The bent wire carries current I , as shown the Figure . What is the magnetic field at point P , at distance d directly opposite the 90 o bend (k = µ 0 /4 π )? Problem 2: Two semi-infinite straight pieces of wire are connected by a circular loop segment of radius R as shown in the Figure . If extrapolated to their intersection point straight wires would form a 30 o angle. If the wires carry a current I , what is the magnitude of the magnetic field at the center of the circular arc (k = µ 0 /4 π )? Problem 3: Three concentric current loops have radii R , 2R , and 3R , as shown in the Figure . The loop with radius 2R carries a current of 2I and the loop with radius 3R carries a current of 3I in the same direction ( counter-clockwise ). If the net magnetic field at the center of the three loops is zero, what is the magnitude and direction of the current in the loop with radius R ? P I d B A I 30 o 2I 3I 2R R 3R

PHY2061 R. D. Field Problems Chapter 33 Page 2 of 6 Problem 4: Two semi-infinite straight pieces of wire are connected by a circular loop segment of radius R as shown in the Figure . If the two straight pieces of wire are perpendicular to each other and if the circuit carries a current I , what is the magnitude of the magnetic field at the center of the circular arc (k = µ 0 /4 π )? Problem 5: An infinitely long straight wire carries a current I 1 , and a wire loop of radius R carries a current I 2 as shown in the Figure . If I 1 = 4I 2 , and if the net magnetic field at the center of the circular loop is zero, how far is the center of the loop from the straight wire?
