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 degrees, using 15 degree steps, and recorded the voltage read by the photodetector. We then repeated the previous procedure, but with a current of -3.0 amps running through the solenoid, therefore changing the magnetic field. Magnetic field can be calculated from current using \ref{magneticfield}  \begin{equation}  \label{magneticfield}  B=11.1I \frac{mT}{A}
