RECOMMENDED: Work through example 22.3 on page 734. Calculating
magnetic field from bending of an electron beam. EXAMPLE: based on problem 21, page 758 A rectangular coil is hinged so that it can
turn around one side that is parallel to the
yaxis. The sides parallel to the yaxis are
0.40 m in length and the sides
perpendicular to the yaxis are 0.30 m in
length. The coil consists of 100 tightly
wrapped turns and the angle between the
plane of the coil and the x—axis is 30°. A
current of 1.2 A circulates as shown. A
magnetic field of 0.80 T points in the x
direction. What is the torque on the coil? i z,
