In 1829 and again in 1830, Zantedeschi published papers on the production of electric currents in closed circuits by the approach and withdrawal of a magnet, thereby anticipating Michael Faraday's classical experiments of 1831.[1]
He also thought that he had detected, in 1838, a magnetic action on steel needles by ultraviolet light. Though this effect was not confirmed, a connection between light and magnetism was suspected so many years before the announcement in 1867 by James Clerk Maxwell of the electromagnetic theory of light.
In a tract of 16 pages, published in 1859, Zantedeschi defended the claims of Gian Domenico Romagnosi to the discovery in 1802 of the magnetic effect of the electric current, a discovery which is usually accredited to Hans Christian Ørsted in 1820. Zantedeschi's experiments and papers on the repulsion of flames by a strong magnetic field (discovered by Michele Alberto Bancalari of the Pious Schools in 1847) attracted general attention at the time.
In his later years Zantedeschi dictated an autobiography which is kept in the archives of the Academy of Verona. His principal works are: Ricerche sul termo-elettricismo dinamico (1838) and Trattato del Magnetismo e della Elettricità (1843).
