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 y-axis. The sides parallel to the y-axis are 0.40 m in length and the sides perpendicular to the y-axis 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, @Anecz I 0x3mxd7v‘trw10, ’97”: MW : /'00X/«2/?s(0‘/2m7: Lama/v0 Wow/w gavva A A A 7 Q/S/M XE /Z’/‘/Z//g/5’\4500: #0409”? Xoig’fk Shad“ ; 7/7?
