Hi,(adsbygoogle = window.adsbygoogle || []).push({});

My Question:

A rectangular loop of wire lies in the same plane as a straight wire, as show in Fig. 20-57. There is a current of 2.5A in both wires. Determine the magnitude and direction of the net force on the loop.

where the width is 10.cm and width of the box is 5.0 cm and distance from the rectangular loop and the straight wire is 3.0 cm.

My Work

F=((mu constant)(I)^2(length))/(2pi(distance))

F=((4pi x 10^-7 Tm/A)(2.5A)^2(.10m))/(2pi(.05m))

F=2.5 x 10^-6 N

but the answer in the back of the book gives F=2.6 x 10^6

What did I do wrong

Thank You
