Question
previous 9of 11 I n What torque acts on the loop? Express your answer using two significant figures. Exercise 27.44 The plane of a rectangular loop of wire with a width of50cn and a height of 8.0 cm is parallel to a magnetic field of magnitude 0.20 T. The loop carries a current of 6.6 A | N.m Submit My Answers Give Up Part B What is the magnetic moment of the loop? Express your answer using two significant figures. A-m2 Submit My Answers Give Up Part C What is the maximum torque that can be obtained with the same total length of wire carrying the same current in this magnetic field? Express your answer using two significant figuresExplanation / Answer
(a) what torque acts on the loop?
= IBAsin = IBwhsin(90)
= 6.6*0.20*0.05*0.08*sin(90) = 0.00528Nm
(b) What is the magnetic moment of the loop?
= IA =Iwh =6.6*0.05*0.08 = 0.0264 Am^2
(c) What is the maximum torque that can be obtained with the same total length of wire
carrying the same current in this magnetic field?
= IB(w+h)^2/
= 6.6*0.20*(0.05+0.08)^2/ = 7.100*10^-3 Nm
