Ampere's Circuital Law

The video tutorial explains the relationship between current and magnetic fields using Biot-Savart's and Ampere's Laws. It describes how to calculate the magnetic field around a current-carrying conductor using Ampere's Law, emphasizing the importance of sign conventions and the right-hand rule. The tutorial also discusses the concept of cylindrical symmetry in magnetic fields and highlights the limitations of Ampere's Law, particularly in scenarios involving circular loop conductors.
