Question

In the figure, a rectangular loop carrying current lies in the plane of a uniform magnetic field of magnitude 0.0454 T. The loop consists of a single turn of flexible conducting wire that is wrapped around a flexible mount such that the dimensions of the rectangle can be changed. (The total length of the wire is not changed.) As edge length x is varied from approximately zero to its maximum value of approximately 4.50 cm, the magnitude of the torque on the loop changes. The maximum value of is 5.21 × 10-8 N*m. What is the current in the loop?

Explanation / Answer

t = NBIA

when x = 4.5 cm it wil be maximum 9 cm

square = 9/4 cm

maximum area = 2.25^2 x 10^-4 =

N = 1

I = t/BA

I = 2.267 x 10^-3 A
