FAQ
Frequently Asked Questions
Yes, the standard form applies to magnetostatics (steady currents). For time-varying currents, modifications are needed.
Jean-Baptiste Biot and Félix Savart were French physicists who experimentally discovered the law in 1820.
Biot-Savart law is used to calculate magnetic field from a current element directly, while Ampère's law relates magnetic field to total current through a loop.
Not directly; for moving point charges, a similar formula exists (Biot-Savart law for a point charge), derived from the current element version.
A fundamental law of magnetostatics that describes the magnetic field generated by a steady electric current.
Biot-savart law is usually technical/scientific in register.
Biot-savart law: in British English it is pronounced /ˌbiːəʊ səˈvɑː lɔː/, and in American English it is pronounced /ˌbiːoʊ səˈvɑːr lɔː/. Tap the audio buttons above to hear it.
