-Kept \textit{-Kept  polarization time constant (4s), varied, current, and saw no change in frequency within error of oscilloscope ($1.852 kHz /pm 0.018 kHz$)\\ -Kept polarization time constant at 5s, varied current, measured amplitude at three peaks of the precession data corresponding to t=0 ms, t=50 ms, and t=100 ms, corresponding to time after the polarization field is no longer applied. We then fit data to eqn (something) which tells us relationship between time and magnetization.\\  - -Kept current constant and varied polarization, measuring amplitude and therefore magnetization. We could see find our saturation polarization time this way, as the amplitude eventually stops increasing.\\  -Then kept polarization time constant at 10s (saturation) and varied current, recording amplitude. In this way we can find dependence of magnetization on magnetic field.\\}  We could vary the polarization time and the current (and therefore magnetic field) to see their effects (if any) on precession frequency,
