\subsection{Varying the Polarization Field}  We also varied magnetic field by varying current to the solenoid, keeping all other values constant, and measured precession frequency. We found there to be no dependence of precession frequency on polarization field, as expected and predicted by Eq.~\ref{eq:precession}. We expect the magnetization to vary according to Eq.~\ref{eq:tanh} when we artificially increase Earth's magnetic field, using a constant polarization time (which was in this case 10 seconds), as seen in Fig.~\ref{fig:polarizationtime10s}. Our data was initially We  plotted our data  against voltage, not magnetization, but magnetization by using  Eq.~\ref{eq:tanh}allows us  to find magnetization as we can calculate $\mu$ using \begin{equation}  \label{eq:mu}  \mu=\gamma\hbar\sqrt{I(I+1)}
