2. A rectangular loop of wire has dimensions 0.500 m by P 0.300 m. The loop is pivoted at the x axis and lies in the xy plane as shown in Figure P29.52. A uniform mag- netic field of magnitude 1.50 T is directed at an angle of 40.0° with respect to the y axis with field lines parallel to the yz plane. The loop carries a current of 0.900 A in the direction shown. (Ignore gravitation.) We wish to evaluate the torque on the current loop. (a) What is the direction of the magnetic force exerted on wire seg- ment ab? (b) What is the direction of the torque associ- ated with this force about an axis through the origin? (c) What is the direction of the magnetic force exerted on segment ed? (d) What is the direction of the torque associated with this force about an axis through the ori- gin? (c) Can thc forces examined in parts (a) and (c) combine to cause the loop to rotate around the x axis? (f) Can they affecct the motion of the loop in any way? Explain. (g) What is the direction of the magnetic force exerted on segment be? (h) What is the direction of the torque associated with this force about an axis through the origin? (i) What is the torque on segment ad about an axis through the origin? (j) From the point of view of Figure P29.52, once the loop is released from rest at 40.0° Figure P29.52
