What current must be maintained in a square loop (50 cm on a side) to create a torque of 1.0 N / m about an axis through its center and parallel to one of its sides when a magnetic field of magnitude 70 mT is directed at 40 to the plane of the loop?
a. 66 A
b. 89 A
c. 61 A
d. 75 A
e. 37 A

Question 2

a. 3.2 ILB
b. 5.0 ILB
c. 4.2 ILB
d. 3.6 ILB
