Question

A rectangular loop of wire is sitting next to a straight wire, as shown in the figure below.

There is a current of I = 2.71 A in both wires. Assume that a = 2.78 cm, b = 5.37 cm and L = 11.0 cm. What is the magnitude on the net force on the loop?
(in N)

A: 5.9710-7 B: 8.6610-7 C: 1.2610-6 D: 1.8210-6 E: 2.6410-6 F: 3.8310-6 G: 5.5510-6 H: 8.0510-6 A rectangular loop of wire is sitting next to a straight wire, as shown in the figure below.

Explanation / Answer

Fnet on loop = Ftop + F boottom

Fnet = (uoi1i1L/2pi)(1/R1 -1/R2)

Fnet = ( 4pi e-7 * 2.71*2.71 * 0.11/2pi)(1/0.0278 - (1/0.0278 +0.0537)

Fnet = 3.83 *10^-6

option F it is
