Light Polarization Using Ferrofluids and Magnetic Fields

Figure 6

The magnetic field of two cylindrical magnets, placed side by side with poles in opposition, as it is shown in the diagram (a), one magnet with 900 Gauss and the small one with 200 Gauss. The pattern obtained with the Ferrocell is shown in (b) with the small magnet at the bottom. (c) presents the simulation for this compound magnet.
