Faraday effect
Principle: The angle of rotation of the polarisation- plane of plane polarized light through a flint glass rod is found to be a linear function of the product of the mean flux-densitiy and the length of the optical medium. The factor of proportionally, called Verdet's constant, is investigated as a function of the wavelength and the optical medium.
Tasks: 1. To determine the magnetic fluxdensitiy between the pole pieces using the axial Hall probe of the teslameter for different coil currents. The mean flux-density is calculated by numerical integration and the ratio maximum fluxdensity over mean flux-density established. 2. To measure the maximum fluxdensity as a function of the coil current and to establish the relationship between mean flux-density and coil current anticipating that the ratio found under 1. remains constant. 3. To determine the angle of rotation as a function of the mean fluxdensity using different colour filters. To calculate the corresponding Verdet's constant in each case. 4. To evaluate Verdet's constant as a function of the wavelength.
