\subsection{Direct Method Calculation}  \begin{eqnarray}  V_{c}&=&\frac{1}{L}\times V_{c}&=&\frac{1}{L}\cdot  \frac{\Delta\theta}{\Delta B}\\ %$$\frac{\Delta\theta}{\Delta B}=\frac{\Delta V}{\Delta B} \times \frac{\Delta \theta}{\Delta V}$$  \theta_{B}&=&104 degrees; \theta_{0}=108 degrees\\  \Delta\theta&=&\theta_{B}-\theta_{0}=-0.069 radians\\  \Delta B&=&-3A\times B&=&-3A\cdot  11.1\frac{mT}{A}=-33.3mT\\ \frac{\Delta\theta}{\Delta B}&=&\frac{-0.069radians}{-33.3mT}=0.00207\frac{radians}{mT}=2.07\frac{radians}{T}\\  V_{c}&=&\frac{1}{L}\times V_{c}&=&\frac{1}{L}\cdot  \frac{\Delta\theta}{\Delta B}=\frac{1}{0.1m}\times B}=\frac{1}{0.1m}\cdot  2.07\frac{radians}{T}=20.7\frac{radians}{T \cdot m} \end{eqnarray}
