SK058 Faraday Effect with He-Ne Laser

Faraday Effect with He-Ne Laser If a transparent isotropic material is placed in a strong magnetic field and linearly polarized light is transmitted in the direction of the magnetic field, the plane of polarization of linearly polarized light rotates by an angle. Features: All electrical connections are made using 4mm safety plugs & sockets. Compact & portable electromagnet. High current DC power supply with safety features like short circuit protection, over heat protection etc. Saddle can hold rod from 8 to 15mm. Heavy, rigid and stable Triangular Optical bench (made of Al extrusion). Height and level adjustment screws (made of SS) Analyser/Polarizer with 0 ± 90° graduation. He-Ne laser with built-in power supply. Objectives: Observing the rotation of the polarization plane when polarized monochromatic light passes through flint glass under influence of a magnetic field. Determining Verdet’s constant from the relation between rotation angle and magnetic flux.
