Magnetic Field and Right-Hand Rule

The video tutorial introduces the Biot-Savart Law, explaining its experimental basis and the equation that describes the magnetic field created by a current-carrying wire. The right-hand rule is used to determine the direction of the magnetic field, and the effect of distance on the field's magnitude is discussed. An alternate right-hand rule is introduced to simplify understanding the magnetic field around wires. The tutorial concludes with a summary of the key points covered.
