Faraday's law,

physical law stating that the number of molesmole,
in chemistry, a quantity of particles of any type equal to Avogadro's number, or 6.02×1023 particles. One gram-molecular weight of any molecular substance contains exactly one mole of molecules.

. The number of faradays required to produce one mole of substance at an electrode depends upon the way in which the substance is oxidized or reduced (see oxidation and reductionoxidation and reduction,

). For example, in the electrolysis of molten sodium chloride, NaCl, one faraday, or one mole, of electrons is transferred at the cathode to one mole of sodium ions, Na+, to form one mole of sodium atoms, Na, while in the electrolysis of molten magnesium chloride, MgCl2, two faradays of electrons must be transferred at the cathode to reduce one mole of magnesium ions, Mg+2, to one mole of magnesium atoms, Mg.

For example, I, and presumably many others, have been led by commentaries on the Treatise to believe that Maxwell did not write down Faraday's law of induction (induced electromotive force) explicitly in his Treatise and that it was Heaviside and Hertz who first expressed "Maxwell's equations" in their more familiar contemporary form.
In this case, on the contrary, Ampere-Maxwell law is carried out, but Faraday's law isn't.
