Ampère's circuital law

In classical electromagnetism, Ampère's circuital law, discovered bi André-Marie Ampère in 1826,[1] relates the integratit magnetic field aroond a closed luip tae the electric current passin through the luip. James Clerk Maxwell derived it again uisin hydrodynamics in his 1861 paper On Physical Lines of Force an it is nou ane o the Maxwell equations, which form the basis o classical electromagnetism.
