Observe the effect of a magnetic field on the polarization light in a dispersive medium.
- Measure the Verdet’s constant of a given dispersive material
- Modular U-Core design with precise optical alignment
- Sensitive light meter allows precise measurement of the amount of rotation of plane polarization
When linearly polarized light passes through an optical medium in a region of the strong magnetic field, the plane of polarization of linearly polarized light rotates by an angle. The angle of rotation of plane-polarized light is proportional to the length of the optical medium and component of the magnetic field in the direction of light. The factor of proportionality is medium-specific and is called Verdet’s constant and this effect is known as the Faraday Rotation or Faraday Effect.
Discovered by Michael Faraday in 1845, the Faraday effect was the first experimental evidence that light and electromagnetism are related. In the experimental setup, the optical medium is an SF6 glass cube.
