Item 9 A single-turn square loop of side Lis centered on the axis of a long solenoid. In addition, the plane of the square loop is perpendicular to the axis of the solenoid. The solenoid has 1160 turns per meter and a diameter of 6.45 cm and carries a current of 2.65A Find the magnetic flux through the loop when L 2.75 cm Submit My Answers Give Up ncorrect, Try Again; 5 attempts remaining Part B Find the magnetic flux through the loop when L 6.45 cm Submit My Answers Give Up incorrect; Try Again; 4 attempts remaining Part C Find the magnetic flux through the loop when L 3.0 cm.

Answer 1

N =1160 turns, d = 6.45 cm , r = 3.225 cm,I = 2.65 A

B = uoNI/2pi*r

flux phi = BA = (uoNI/2pi*r)*L^2

(A) L = 2.75 cm

phi = (2*10^-7*1160*2.65/(2*3.14*0.03225))*0.0275^2

phi = 2.3*10^-6 Wb

(B) L = 6.45 cm

phi = (2*10^-7*1160*2.65/(2*3.14*0.03225))*0.0645^2

phi = 1.263*10^-5 Wb

(C)L =13 cm

phi = (2*10^-7*1160*2.65/(2*3.14*0.03225))*0.13^2

phi = 5.13*10^-5 Wb
