Biot–Savart law

In physics, specifically electromagnetism, the Biot–Savart law (/ˈb səˈvɑːr/ or /ˈbj səˈvɑːr/) is an equation describing the magnetic field generated by an electric current. It relates the magnetic field to the magnitude, direction, length, and proximity of the electric current. The law is valid in the magnetostatic approximation, and is consistent with both Ampère's circuital law and Gauss's law for magnetism. It is named after Jean-Baptiste Biot and Félix Savart who discovered this relationship in 1820.
