Abstract
The research aimed to design and create Faraday's rotation system as a tool to characterize the magneto-optic properties of vegetable oil. The measured magnitude were the intensity of light, the magnitude of the magnetic field, and the change in the rotation angle of polarization. Measurement of light intensity was carried out using BH1750 as a light sensor, magnetic field measurement was carried out using Gauss meter. Changes in the rotation angle of polarization were made by the stepper motor which drove the lens of the analyzer which had been geared. The light source used was an RGB laser with a power 300mW. Data were collected by the initial condition of the angle between polarizer and analyzer lens at 45°. It can be concluded that Faraday rotation experiment is affected by heat produced by the solenoid and olive oil has magneto-optic property.
