## Homework Statement

The x, y, and z components of a magnetic field are Bx = 0.10 T, By = 0.13 T, and Bz = 0.17 T. A 25 cm wire is oriented along the z axis and carries a current of 4.5 A. What is the magnitude of the magnetic force that acts on this wire?

## Homework Equations

F=ILB (sin theta)

## The Attempt at a Solution

Well, I have

F= (4.5A)(25e-2 m)(B?????) (sin 90)

I don't know which value for B to use or how to incorporate the three values together. I tried using the three B values to find three different force values, but I don't know how to "add" the three together.

This may be totally wrong but when I plugged Bx, By and Bz into the above equation I got

Fx=.01125N

Fy=.01462N and

Fz=.01913N

...but I'm pretty sure this is wrong

Please help
