Question
consider a 150 turn (10%) Problem 7: Consider a 150 turn square loop of wire/ 7 cm on a side that carries a 56 A current in a 1.75 T field Randomized Variables 17 cm 1- 56 A B-175T Grade Summary Deductions Potential 50% Part (a) What is the maximum torque on the loop of wire in Nm? 67 88% 7 8 9 HOME sino l cos() | tan() |1 cotan asinacos) atan acotan) sinh) Submissions Attempts remaining: 7 4%per attempt) detailed view sh tanhcotanh ODegrees ORadians END 4% BACKSPACE DEL CLEAR Hints: deducion per tint Hints remaining 2 I give upl Feedback: deduction per feedback. be e in N'rm when the angle between the feld and the normal to the plane of the loop 0 is d and the normal to the plane of the loop is 607Explanation / Answer
(A) torque = NIA x B = N I A B sin(theta)
maximum torque = N IA B
= (150) (56) (0.17^2) (1.75)
= 424.83 N m
(B) when theta = 6 deg
torque = 424 .83 sin6
= 44.4 N m
