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
