Question

Responses dep 15372216 Two insulated current-canrying wires (wire 1 and wire 2) are bound together with wire ties te form a two-wire unit. The wines are zsa 8.00 A and the other wire carries a current in the opposite direction. The two-wire unit is placed in a uniform magnetic field of 0.400 T such that the angle between the direction of Ma and the magnetk field is 71,5. While we dont know the current in wire 2, we do know that it is of the net force experienced bythe two-wire unit is 1.50 N, determine the current in wire 2. Reading save Progress Asshown the figure, a rectangular loop with a length of 20.0 am and a w 15.0 cm. has 20 turns and carries a ourrent of 0.17A counterclockwise around the loep when viewed from the powitive raais. rempectively.) to the xt plane) magnetic field of magnitude 0.045 T is at an angle of relative to the perpendioular to the looo (the posilvex axis). Assume the length and width are measured along the and v-axes,

Explanation / Answer

Given that Fnet = F1-F2 = 3.5 N

F1 = i*l*B*sin(theta) = 8*2.80*0.4*sin(73.5) = 8.59 N

F2 = i*l*B*sin(theta) = i*2.80*0.4*sin(73.5) = 1.07*i

8.59-(1.07*i) = 3.5

current in wire 2 is i = 4.75 A
