be Acrobat Reader DC w Help 4 19 ) : 117% loop about the axis of rotation, which is along the left side of the square as indicated by the dashed line in the figure? Answer in units of N m. Question 13, chap 129, sect 4. part 1 of 1 10 points A circular loop of radius 4.77 cm contains 66 turns of tightly wound wire. If the current homework 06 HIGHTOWER, KORDELI Due: Apr 8 2018, 11:00 pm (Central time) 5 in the windings is 0.591 A and a constant magnetic field of 0.498 T makes an angle of 66.2° with a vector perpendicular with the loop, what torque acts on the loop? Answer in units of N m BA 3,Explanation / Answer
Torque is given by:
T = N*i*A*B*sin theta
Using given values:
sin 66.2 deg = 0.9149
A = pi*r^2 = pi*0.0477^2 m^2
T = 66*0.591*pi*0.0477^2*0.498*0.9149
T = 0.127 N-m
