## Homework Statement

A segment of wire carries a current of 20 A

along the x axis from x = −6 m to x = 0 and

then along the z axis from z = 0 to z = 7.2 m.

In this region of space, the magnetic field is

equal to 51 mT in the positive z direction.

What is the magnitude of the force on this

segment of wire?

## Homework Equations

Fb= ILBsintheta

## The Attempt at a Solution

Fb = ( 20 A ) (7.2m ) ( .051m )

the question asked for " the magnitude of the force on THIS SEGMENT of wire" so i thought to just plug in 7.2m but it turned out to be wrong so i added the 6m as well but it was wrong again. help =[
