For a current of \unit[0.1]{A}, we expect a rotation of a few$\times10^{-4}$ radians. This is a pretty small angle and it will require a special technique to detect. -We are going to take polarized laser light and direct it through the glass +We are going to take the polarized laser light and direct it through the glass rod, which is inserted into the center of the solenoid. The beam will then pass through a second polarizer with the transmission axis at an angle $\theta$ with respect to the initial polarization of the laser. The intensity of the transmitted light will then depend on the sum of the angle $\theta$ and the additional rotation $\phi$ caused by the magnetic field: \begin{eqnarray} |
