Formula and explanation
Formula: B = (μ₀ I R²)/(2(R² + x²)^(3/2)). Conditions: Single - turn circular loop of radius R, steady current I, vacuum or non - magnetic medium, on the axis at distance x from the center. Explanation: At the center ( x = 0 ), the formula simplifies to B₀ = (μ₀ I)/(2R). The field direction is along the axis, determined by the right - hand rule.
