Magnetostatics: Lorentz Force and Magnetic Field

This lecture covers the observation of a charged particle in motion near a magnet or current-carrying wire, experiencing the Lorentz force. It explains the magnetic field as a vector dependent on the magnet or current in the wire and the charge's location. The lecture details the magnetic field's unit, the tesla, and its application to an infinite straight current-carrying wire. It also discusses the principle of superposition for the magnetic field and the change in the Lorentz force direction under different replacements. The concept of work in the presence of electric and magnetic fields is explored, along with the motion of a charged particle in a magnetic field.
