WebSep 12, 2024 · The Biot-Savart law states that at any point P (Figure 12.2. 1 ), the magnetic field d B → due to an element d l → of a current-carrying wire is given by. (12.2.1) 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. (12.2.2) μ 0 = 4 π × 10 − 7 T ⋅ m / A. in the SI system. WebFeb 1, 2001 · Analytic expressions for the magnetic induction (magnetic flux density, B) of a simple planar circular current loop have been published in Cartesian and cylindrical coordinates [1,2], and are also known implicitly in spherical coordinates [3]. In this paper, we present explicit analytic expressions for B and its spatial derivatives in Cartesian, …

Direct evidence of secondary reconnection inside filamentary ... - Nature
WebInside this filamentary current (Fig. 4a–f), B L changed sign from negative to positive (Fig. 4a), B M exhibited a bipolar variation with respect to the strong background field (~50 nT), and the current density peaked at the reversal point of B L at 09:01:05.6 UT (Fig. 4b). It shows that the spacecraft crossed the thin filamentary current. WebA Birkeland current (also known as field-aligned current) is a set of electrical currents that flow along geomagnetic field lines connecting the Earth's magnetosphere to the Earth's high latitude ionosphere. In the Earth's magnetosphere, the currents are driven by the solar wind and interplanetary magnetic field and by bulk motions of plasma ...
