I am a high school student experimenting with the Verdet constant of materials and how it affects the polarization of light in magneto-rotation. I have trouble acquiring the proper materials for this experiment. Here is what I have so far: -AC/DC Power Supply -Gaussmeter -Optical laser under 5MW -Neodymium Magnets -Solenoid -Various samples that light can pass through I need polarisers and light analyzers to complete the apparatus. I also think the neodymium magnets will be too weak to create a magnetic field surrounding my sample. I would appreciate any advice on sustainable polarizers, analysers, and magnets that are relatively cheap (under $60).
