The ferrocell is an optical viewing device that interacts with a magnetic field and one or more light
sources to produce a real-time visual light display. Although this device has been extensively studied
by several researchers, a proper computer simulation replicating this optical effect has not yet been
presented. Using numerical methods and the law of reflection, a computer simulation was developed
that shows that the light patterns as seen in the ferrocell are primarily caused by light reflections
off the ferrofluid nano-particles that self organize into needle-like filaments and align along magnetic
flux lines in the presence of a magnetic field.
