Magnetostriction with the Michelson interferometerelson interferometer Principle With the aid of two mirrors in a Michelson arrangement, light is brought to interference. Due to the magnetostrictive effect, one of the mirrors is shifted by variation in the magnetic field applied to a sample and the change in the interference pattern is observed. Benefits - See that magnetic fields can change the geometry of objects
- Use a Michelson interferometer to measure quantitatively this most subtile effect
- Set up the instrument by yourself from separate components
Tasks - Construction of a Michelson interferometer using separate optical components.
- Testing various ferromagnetic materials (iron and nickel) as well as a non-ferromagnetic material (copper), with regard to their magnetostrictive properties.
Learning objectives - Interference
- Wavelength
- Diffraction index
- Speed of light
- Phase
- Virtual light source
- Ferromagnetic material
- Weiss molecular magnetic fields
- Spin-orbit coupling
