• Steady Currents and Magnetostatic Fields: From the Biot–Savart Law to curl B = μ0 JFrom current density and charge conservation, via the Biot–Savart law, to the two equations of magnetostatics: div B = 0 and curl B = μ0 J, the curl being circulation per unit area.PhysicsElectromagnetismUndergraduateMagnetostaticsCurrent densityBiot-Savart lawAmpère's lawVector calculus~28 min
