Jean-Baptiste Biot
1774 – 1862
Co-authored the law of the magnetic field from a current.
A French physicist who, with Félix Savart, formulated the law of the magnetic field produced by an electric current in 1820 — the Biot–Savart law that underlies magnetics and antenna theory.
He also made the first hot-air-balloon ascent for scientific measurement. The magnetic and RF tools here rely on the field law he co-authored.
