In physics, particularly electromagnetism, the Biot–Savart law ( /ˈbiːoʊ səˈvɑr/ or /ˈbjoʊ səˈvɑr/) is an equation that describes 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.

Famous quotes containing the word law:
“Nobody dast blame this man.... For a salesman, there is no rock bottom to the life. He dont put a bolt to a nut, he dont tell you the law or give you medicine. Hes a man way out there in the blue, riding on a smile and a shoeshine. And when they start not smiling backthats an earthquake. And then you get yourself a couple of spots on your hat, and youre finished. Nobody dast blame this man. A salesman is got to dream, boy. It comes with the territory.”
—Arthur Miller (b. 1915)
