Formula and explanation
Formula: dB = (μ₀)/(4π) (I dl × r)/(r³) Conditions: In vacuum or uniform linear media, for steady currents. Explanation: The fundamental law for calculating the magnetic field generated by a steady current. The magnetic induction dB produced by a current element I dl at a point P is proportional to the current element, inversely proportional to the square of the distance r from the element to P, and its direction is given by the cross product dl × r.
