Magnetic Field Effect on Chemical Wave Propagation from the Belousov-Zhabotinsky Reaction

Effects of magnetic field (maximum field, 4 and 93 T-2 m(-1)) on the propagation speed of a chemical wavefront from the Belousov-Zhabotinsky reaction were studied in a thin glass tube. The downward and upward speed and the horizontal one are, respectively affected significantly by vertical and horizontal magnetic fields. Observations of the wavefront shape in magnetic fields showed that the magnetic force-induced convection causes the observed effects.
