Homework Statement
Suppose that the magnetic field in some region has the form B=kz[tex]\hat{x}[/tex] (k constant). Find the force on a square loop (side a) , lying in the yz plane and centered at origin if it carries current I flowing counterclockwise, when you look down the x-axis.
Homework Equations
The Attempt at a Solution
I understand how to work out the math, its just that "look down the x-axis" tidbit at the end. when it says you're looking DOWN the x-axis, does that mean standing on the negative end looking down the positive, or vice-versa, cause that's quite important for the problem.
