The infinitesimal magnetic induction d B → Īre, respectively, the perpendicular (transverse, divergence-free) and parallel (longitudinal, curl-free) components. Magnetic induction d B at point r due to infinitesimal piece d s (red) of wire (blue) transporting electric current i. Later Laplace gave an improved and generalized mathematical formulation of their result. Simultaneously they published this in a short note.

Son intensité est réciproque à la simple distance). ( la force qui sollicite la molécule est perpendiculaire à cette ligne et à l'axe de fil. At a meeting of the Académie des Sciences on 30 October 1820, Biot and Savart announced that the magnetic force exerted by a long conductor on a magnetic pole falls off with the reciprocal of the distance and is orientated perpendicular to the wire François Arago demonstrated the discovery at the French Académie des Sciences (11 September 1820), which inspired Jean-Baptiste Biot and André-Marie Ampère to investigate the effect further. He wrote a Latin publication which he sent round Europe. The Danish physicist Ørsted noticed in April 1820, while experimenting with the Voltaic pile, an effect of an electric current on a permanent magnet. By integrating Laplace's equation over an infinitely long wire, the original integral form of Biot and Savart is obtained. Laplace gave a differential form of their result, which now often is also referred to as the Biot-Savart law, or sometimes as the Biot-Savart-Laplace law. Biot and Savart interpreted their measurements by an integral relation. Equation (337) is known as the Biot-Savart law after the French physicists Jean Baptiste Biot and Felix Savart: it completely specifies the magnetic field.

In physics, more particularly in electrodynamics, the law first formulated by Jean-Baptiste Biot and Félix Savart describes the magnetic induction B (proportional to the magnetic field H) caused by a direct electric current in a wire. 4 Magnetic field on axis of circular current.MISN-0-125 The Ampère–Laplace–Biot–Savart Law by Orilla McHarris and Peter Signell for Project PHYSNET.Media related to Biot-Savart law at Wikimedia Commons.McGraw Hill Encyclopaedia of Physics (2nd Edition), C.B.Encyclopaedia of Physics (2nd Edition), R.G.Physics for Scientists and Engineers - with Modern Physics (6th Edition), P.Woan, Cambridge University Press, 2010, ISBN 978-7-2.

What is the Formula of Biot-Savart’s Law Consider a current carrying wire ‘i’ in a specific direction as shown in the above figure. This segment is taken as a vector quantity known as the current element. 14: The Magnetic Field in Various Situations What is Biot-Savart Law Biot-Savart’s law is an equation that gives the magnetic field produced due to a current carrying segment.

In a similar manner the Coulombs law relates electric fields. The presentation in Griffiths is particularly thorough, with all the details spelled out. The BiotSavart law relates the magnetic fields to the electric currents, which are their sources. Biot Savart Law relates magnetic field to direction, magnitude, proximity, length of the electric current.
