Biot-Savart Law, Magnetic Field, Electric Current, Examples – Physics

This video explains the Biot-Savart law, including the definition, derivation of the formula in both vector and scalar form, sign convention using the right hand rule, and what it is. It also explains how to calculate the magnetic force on a wire carrying current in a magnetic field. Worked examples are covered, including magnetic field at the center of a wire loop and along the bisector of an infinite wire.
