Formula and explanation
Formula: L B · dl = μ₀ ∑ I(enc). Conditions: Magnetic field produced by steady currents, arbitrary closed path L (chosen for calculational convenience). Explanation: This law states that the line integral of the magnetic induction B around any closed loop is equal to μ₀ times the algebraic sum of the currents enclosed by the loop. The sign of the current is determined by the right - hand rule relative to the loop's direction. Used to calculate magnetic fields with high symmetry.
