I_{rms}=0.6137\times V_{rms}  \end{equation}  %$$B=11.1\times\frac{mT}{A}\times I$$  $$Gain=G_{preamplifier}\times %$$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}$$ %$$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.
