The figure shows the orientation of a rectangular loop consisting of 80 closely wrapped turns each carrying a current I. The magnetic field in the region is () mT. The loop can turn about the y axis. If = 30, a = 0.40 m, b = 0.30 m, and I = 8.0 A, what is the magnitude of the torque exerted on the loop?

a.
2.5 N m

b.
1.5 N m

c.
3.1 N m

d.
2.7 N m

e.
0.34 N m

Question 2

The figure shows the orientation of a flat circular loop consisting of 50 closely wrapped turns each carrying a current I. The magnetic field in the region is directed in the positive z direction and has a magnitude of 50 mT. The loop can turn about the y axis. If = 20, R = 0.50 m, and I = 12A, what is the magnitude of the torque exerted on the loop?
