\end{equation}  We can further simplify equation \ref{eq4} by making two careful choices about the experimental setup. First, we choose to investigate the point exactly halfway between the coils, as shown in Figure \ref{fig1}, such that $\textit{z}=\frac{\textit{d}}{2}$. Second, we set the coils such that the separation distance \textit{d} is the same as the radius \textit{R}. The denominator of equation \ref{eq4} then becomes $(\textit{R}^2 + (\frac{\textit{R}}{2})^2)^\frac{3}{2}$. Substitutting back into equation \ref{eq4} and canceling we arrive at our final expression for the magnetic field at the center of the Helmholtz configuration:  \being{equation}\label{eq5}  B=8\mu_0\textit{N}\textit{I} B=8  \end{equation}
