Formula and explanation
Formula: dB = (μ₀)/(4π) (I dl × r)/(r³). Conditions: Steady current element I dl in vacuum or non - magnetic medium. Explanation: This law calculates the magnetic induction dB produced by a current element I dl at a point in space. μ₀ is the vacuum permeability, r is the vector from the current element to the field point. The total field is obtained by integration.
