WebThe meaning of BIOT-SAVART LAW is a statement in electromagnetism: the magnetic intensity at any point due to a steady current in an infinitely long straight wire is directly proportional to the current and inversely proportional to the distance from point to wire. WebJan 13, 2024 · The Biot-Savart law states that at any point P (Figure 8.2. 1 ), the magnetic field d B → due to an element d l → of a current-carrying wire is given by. (8.2.1) d B → = μ 0 4 π I d l → × r ^ r 2. The constant μ 0 is known as the permeability of free space and is exactly. (8.2.2) μ 0 = 4 π × 10 − 7 T ⋅ m / A. in the SI system.
