I_{rms}=0.6137\times V_{rms}
\end{equation}
%$$B=11.1\times\frac{mT}{A}\times I$$
$V_{pd, RMS}$ represents the aforementioned RMS value of photodiode voltage.
\frac{d\theta}{dV_{pd}}\right)_{\theta=45} $\frac{d\theta}{dV_{pd}}\right)_{\theta=45}$ is the same as in method 2.
%$$Gain=G_{preamplifier}\times G_{filter}\times G_{lock-in-amplifier}\times G_{lowpass filter}=500\times2\times10\times1=10000$$
%$$V_{Photodiode}=\frac{V_{output}\times1.11}{10000}$$
%We varied the RMS value of the voltage driving the solenoid and recorded the RMS value of the corresponding photodiode voltage.
