Question 1

A rigid rectangular loop, measuring 0.30 m by 0.40 m, carries a current of 5.5 A, as shown in the figure. A uniform external magnetic field of magnitude 2.9 T in the -x direction is present. Segment CD is in the xz-plane and forms a 35° angle with the z-axis, as shown. What is the magnitude of the torque that the magnetic field exerts on the loop?



◦ 1.3 N ∙ m
◦ 1.1 N ∙ m
◦ 1.6 N ∙ m
◦ 1.4 N ∙ m
◦ 0.73 N ∙ m

Question 2

A flat rectangular loop of wire is placed between the poles of a magnet, as shown in the figure. It has dimensions w = 0.60 m and L = 1.0 m, and carries a current I = 2.0 A in the direction shown. The magnetic field due to the magnet is uniform and of magnitude 0.80 T. The loop rotates in the magnetic field and at one point the plane of the loop makes a 30° angle with the field. At that instant, what is the magnitude of the torque acting on the wire due to the magnetic field?



◦ 0.96 N ∙ m
◦ 0.83 N ∙ m
◦ 0.40 N ∙ m
◦ 0.48 N ∙ m
◦ 0.30 N ∙ m
