“…And it's clear that F is always perpendicular to v. Thus, an external magnetic field has the ability to alter the rate of molecular transport of electrochemical species which is called the MHD phenomenon [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The MHD flow in electrochemical systems is conveniently described by the force per unit volume acting on the solution, F MHD (N/m 3 ),…”

The effect of magnetic field on the pitting corrosion susceptibility of pure magnesium was investigated by stochastic approaches. Stochastic models had been applied to simulate pitting corrosion as the combination of two physical processes: pit initiation and pit growth. The results revealed that magnetic field increased the pitting corrosion susceptibility of pure magnesium. For the pit initiation process, the presence of magnetic field changed the mechanism of pit initiation from the parallel birth and death stochastic model (B1) to the parallel birth stochastic model (A3). Magnetic field increased the pit generation rate l while decreased the repassivation rate m, which indicated that magnetic field accelerated the pit initiation process of pure magnesium. For the pit growth process, magnetic field didn't change the pit growth mechanism, but it could decrease the ability of repassivation of pitting corrosion resulting in a great probability for the stable pitting corrosion to grow up with a higher growth rate and finally develop into larger pit cavity.

Some influences of magnetic fields on chemical reactions have been recently studied, but there is no general agreement about the phenomena and their explanation (Fahidy 1983(Fahidy , 1990(Fahidy , 1999Tacken and Janssen 1995;Waskaas 1996;Yamamoto et al 1996Yamamoto et al , 1999Debos et al 2000;Hinds et al 2002;Perov et al 2002Perov et al , 2004Lu et al 2003Lu et al , 2005Coey 2003; Rhen et al 2004;Alemany and Chopart, 2007;Koza et al 2008;Lu and Yang 2008). …”

The rise of magnetochemistry from Ritter to Hurmuzescu

This paper describes the early history of magnetochemistry: the search for chemical effects of magnetism in the nineteenth century. Some early researchers, such as Johann Wilhelm Ritter, attempted to reproduce with magnets the effects that had been produced by electricity and Volta's battery. For several decades, researchers successively reported positive results and denied claims concerning the effect of magnetism in oxidation, electrolysis, reduction of metals from saline solutions, crystallisation, change of colour of vegetable tinctures and other chemical reactions. In the two last decades of the nineteenth century some effects were accepted as real, and a thermodynamic theory of the influence of magnetic fields upon chemical reactions was developed. Finally, Dragomir Hurmuzescu was able to create reproducible experiments and measured the electromotive force between two electrodes, with or without the presence of magnetic fields, confirming the existence of the phenomenon and obtaining results compatible with the theoretical predictions. Afterwards, this magnetochemical effect was accepted as real, but the effect was weak and its practical importance was negligible. The subject was gradually forgotten.
