Linearly polarized light was sent through the solenoid containing a glass tube but without any current flowing through it, passed through the polarizer, and detected by the photodiode. We rotated the polarizer around 360 $360$  degrees, using 15 $15$  degree steps, and recorded the voltage read by the photodetector. We then repeated the previous procedure, but with a current of -3.0 $-3.0$  amps running through the solenoid, therefore changing the magnetic field. Magnetic field can be calculated from current using Equation \ref{magneticfield} \begin{equation}  \label{magneticfield}  B=11.1I \frac{mT}{A}
