## Homework Statement

Consider two parallel conducting wires along the direction of the z axis as shown below. Wire 1 crosses the x-axis at x = -1.10cm and carries a current of 3.50A out of the xy-plane of the page. Wire 2 (right) crosses the x axis at x = 1.10cm and carries a current of 6.20A into the xy plane.

At which value of x is the magnetic field zero? (Hint: Careful with sign)

## Homework Equations

B = u0I / 2pi r

## The Attempt at a Solution

I found the B field values for both wires, but I don't understand how to find where they intersect? Can someone help?

Thanks! The diagram is attached
