Biot–Savartn.

Brit.

/ˌbiːəʊsəˈvɑː/, U.S.

/ˌbioʊsəˈvɑr/

Origin: From proper names. Etymons: proper name Biot, Savart.

Etymology: < the names of Jean-Baptiste Biot (see Biot n.) and Félix Savart (1791–1841), French scientists, who discovered the law (compare the account of a paper read by them in October 1820 at the Academie des Sciences in Ann. de chim. et de physique 15 (1820) 222). Compare German Biot-Savart'sche Gesetz (1861 or earlier), French la loi de Biot-Savart (1887 or earlier).

Physics.

attributive, in the genitive, and with of. Designating the law that the magnetic flux density near a long straight conductor is inversely proportional to the distance from the conductor and directly proportional to the current in the conductor. Also (attributive): of or relating to this law.

1887 London, Edinb., & Dublin Philos. Mag. 5th Ser. 24 405 In conformity with the law of Biot-Savart, a magnetic pole acts upon an element of the current with a force equal to the intensity of the pole divided by the square of the distance to the element.
