Light Polarization Using Ferrofluids and Magnetic Fields

Figure 3

Plots representing the magnetic field using the Gaussmeter. (a) The plot of the magnetic field in the monopolar configuration (also known as unipolar configuration) and (b) the two-dimensional plot of the intensity of the magnetic field. (c) The plot of the magnetic field in the bipolar configuration and (d) the two-dimensional plot of the intensity of the magnetic field. When the magnet is placed at the top of the Ferrocell, the ferrofluid reacts to one of these configurations depending on its position.
