Question: The rectangular loop shown in Fig. 5-33 (P5.4) consists of 20 closely wrapped turns and is hinged along the z-axis. The plane of the loop

The rectangular loop shown in Fig. 5-33 (P5.4) consists of 20 closely wrapped turns and is hinged along the z-axis. The plane of the loop makes an angle of 30o with the y-axis, and the current in the windings is 0.5 A. What is the magnitude of the torque exerted on the loop in the presence of a uniform field B = y2.4 T? When viewed from above, is the expected direction of rotation clockwise or counterclockwise?

1= 0.5 A 20 turns 0.4 m 30 0.2 m Figure P5.4: Hinged rectangular loop of Problem 5.4.
