Volta-electric

The similarity of action, almost amounting to identity, between common magnets and either electro-magnets or volta-electric currents, is strikingly in accordance with and confirmatory of M. Ampere’s theory, and furnishes powerful reasons for believing that the action is the same in both cases; […] I propose to call the agency thus exerted by ordinary magnets, magneto-electric or magnelectric induction.

In these equations v₁, v₂, … v₂₁ denote the volta-electric differences from copper which must be given to part 1, part 2, … part 21 of the surface of the molecule in order that the 21 piezo-electric and pyro-electric coefficients may have their given values […]

The first series of these researches, presented to the Royal Society on 24 November 1831, contained the first account of his discovery of voltaelectric and magnetoelectric induction.
