\newline  We applied four different magnetic fields so we ended up with four Verdet constants. We took the average and used the maximum and minimum to calculate the uncertainty.  In this way, we get:  $$V_{c}=20.43\pm0.058\frac{radians}{T $$V_{c}=20.43\pm0.06\frac{radians}{T  \cdot m}$$ %$$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.
