-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 and amplitude (and therefore magnetization). In order to measure the  frequency, we adjusted the scale of the oscilloscope so that we had at least 10 (but not many more) periods on the oscilloscope display, and measured the frequency for 10 cycles, using the frequency the oscilloscope measured for 10 cycles to determine the frequency of one cycle- the Larmor precession frequency.
