**1. Homework Statement**

A long, straight wire carries a current of 14 A. Next to the wire is a square loop with sides 1.0m in length. The loop carries a current of 2.5A in the same direction as the wire. Calculate the net force acting on the wire.

**2. Homework Equations**

Magnetic Field for long, straight wire: permeability of free space*I/ 2pi*radius

**3. The Attempt at a Solution**

I know that the net force is the two forces from the wire and the loop, but I don't understand how to calculate the 2 different magnetic fields.
