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

A piece of wire is bent to form a circle with radius r. It has a steady current I flowing through it in a counterclockwise direction as seen from the top (looking in the negative z direction).

What is B_z(0), the z component of B at the center (i.e., x = y = z = 0) of the loop?

Express your answer in terms of I, r, and constants like mu_0 and pi.

2. Relevant equations

3. The attempt at a solution

I know this equation:

[tex]\frac{(\mu_0)I}{2(\pi)r}[/tex]

but there is a hint that says I need to find the Integrand.

Thank You.
