Answer 1

The Biot-Savart Law is the absolute foundational equation in magnetostatics mathematically defining the exact magnetic field generated strictly by a tiny steady current element.

d B = \frac{μ _{0} I}{4 π} \frac{d l \times r ^}{r ^{2}} = \frac{μ _{0} I}{4 π} \frac{d l \times r}{r ^{3}}

Where $d B$ is the differential magnetic field vector, $I$ is the steady current, $d l$ is the infinitesimal vector length element of the wire, $r$ is the full position vector pointing from the current element strictly to the observation point, and $r$ is its absolute scalar magnitude.
