FARADAY EFFECT EXPERIMENT WITH HALOGEN LIGHT SOURCE
Item Code : SK063
Principle and Working:
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.
The angle of rotation (Ø) of plane polarized light is proportional to the length (L), magnetic field (B) and Verdet’s constant (V).
- 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 optical bench.
- Height and level adjustment screws.
- Analyser/Polayser with 0 ± 90° graduation.
- 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.
- Verification of the relationship between Verdet’s constant and wavelength.
