- 12.3: Magnetic Field due to a Thin Straight Wire
It relates the magnetic field to the magnitude, direction, length, and proximity of the electric current. The Biot–Savart law is fundamental to magnetostatics. It is valid in the magnetostatic approximation and consistent with both Ampère's circuital law and Gauss's law for magnetism. [2]
Explain how the Biot-Savart law is used to determine the magnetic field due to a thin, straight wire. Determine the dependence of the magnetic field from a thin, straight wire based on the distance from it and the current flowing in the wire.
14 Οκτ 2024 · Biot-Savart law, in physics, a fundamental quantitative relationship between an electric current I and the magnetic field B it produces, based on the experiments in 1820 of the French scientists Jean-Baptiste Biot and Félix Savart. A current in a loop produces magnetic field lines B that form loops.
The equation used to calculate the magnetic field produced by a current is known as the Biot-Savart law. It is an empirical law named in honor of two scientists who investigated the interaction between a straight, current-carrying wire and a permanent magnet.
The Biot-Savart law (BSL) provides a method to calculate the magnetic field due to any distribution of steady (DC) current. In magnetostatics, the general solution to this problem employs Ampere’s law; i.e., ∫CH ⋅ dl = Iencl. in integral form or. ∇ × H = J.
The relationship between the magnetic field contribution and its source current element is called the Biot-Savart law. The direction of the magnetic field contribution follows the right hand rule illustrated for a straight wire.
