Homework Statement
Two parallel wires are positioned at l = 2.76 cm apart. Initially a current I1 = 9.57 A flows up the screen through wire 1, and wire 2 has no current in it.
A current is then sent through wire 2. The magnetic field between the two wires, is found to be 0T.
What is the size of the current flowing through wire 2?
Homework Equations
The Attempt at a Solution
I tried to use
i = 2pi*rB/μ
= 2pi*0.0276x0/4pix10^-7
then I realized the answer is zero but that is totally incorrect. Am I using the correct formula here? Or should I be using
