Question
I would like to see the work shown for these questions.
Physics 212 Exam II Fall 2017 The next two questions pertain to the situation described below. A square loop carries a current I and pivots without friction about the z-axis. A uniform magnetic field B = 2.4 T points in the +x direction, and the loop initially makes an angle 70° with the x-z plane. B=2.4 T d=0.2 m =70° top view of loop plan view of loop 11· The torque on the loop is in the +z direction. rue b. False 12·The magnitude of the current in the loop is measured to be /= 36.5 A. Calculate the magnitude of the torque on the loop. 2 a. = 0.2 N·m b. . 0.9N·m c) = 1.2 N·m 2.2 N·m r= 4.2 N·m 7 of 9 pages (15 problems)Explanation / Answer
given square loop
carries current I
B = 2.4 T
theta = 70 deg
11. torque = BiAcos(theta)
hence form the diagram
the torque is along -z direction
hence this statement id false
12. i = 36.5 A
T = BiAcos(theta)
A = d^2 = 0.2^2
T = 1.1984 Nm
