(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two long parallel wires are a center-to-center distance of 1.50 cm apart and carry equal anti-parallel currents of 1.80 A. Find the magnetic field intensity at the point P which is equidistant from the wires. (R = 4.00 cm).

2. Relevant equations

[tex] B= \frac{u_{0}I}{2\pi r} [/tex] infinite wire

3. The attempt at a solution

Ok I have been workin this problem for a while.

In terms of vectors, the y's cancel out.

For the X direction I get:

[tex] B_{totalx}=\frac{u_{0} I R}{\pi \sqrt( (d/2)^2 +R^2)}[/tex]

I dont get why I am wrong, I took the sum of the b-fields in terms of vectors.

And no the answer is not 0 T!
