Differential form of ampere's circuital law
WebThe flux of the current density through any loop is calculated by evaluating the integral for any surface which spans the loop. According to Ampère's circuital law, this integral depends only on and is completely independent of ( i.e., it is equal to the line integral of around , which depends on but not on ). WebSep 12, 2024 · The differential form of Ampere’s Circuital Law for magnetostatics (Equation 7.9.2) indicates that the volume current density at any point in space is proportional to the spatial rate of change of the magnetic field and is perpendicular to the magnetic field at …
