Biot Savart Law and Magnetic Field around a Current Carrying Wire

The video tutorial introduces the Bio Savart Law, named after French scientists, explaining its experimental basis and application in determining the magnetic field created by a current-carrying wire. The tutorial covers the equation, emphasizing the use of the right-hand rule to find the direction of the magnetic field. It also discusses the magnitude and direction of the magnetic field, including an alternate right-hand rule for easier understanding. The tutorial concludes with a brief mention of the derivation of the magnetic field for an infinitely long wire.
