Light Polarization Using Ferrofluids and Magnetic Fields

Figure 2

(a) The diagram of the measurements using the Hall sensor for the magnetic field of the compound magnets, in order to carry out a comparison with the light patterns observed in the Ferrocell. In (b), there are plots of the magnetic fields for different compound magnets. The coordinate represents a generic coordinate, which can be replaced by and , or it represents the polar coordinate, depending on the magnetic field configuration.
