    Introduction Heaviside-Lorentz units (named for O. Heaviside and H.A. Lorentz) constitute a particular extension of CGS units which are most often useful in theoretical electrodynamics. As a practical system of units, Heaviside-Lorentz falls short due to most measureable quantities being excessively small or big for intuition. Neverless, Heaviside-Lorentz showcases the simplicity and beauty of the…

    18.1 Introduction In this chapter, we will discuss the magnetic field produced by moving charges, such as electrons and ions, and how it affects the motion of other charged particles. Understanding the magnetic field of a moving charge is essential for various applications, including the design of particle accelerators and the analysis of plasma behavior…

    Introduction The permeability of free space, often denoted as , is a physical constant that describes the amount of magnetic field produced per unit of magnetic current in a vacuum. It is one of the fundamental constants in physics and plays a vital role in the study of electromagnetism. Definition and Value The permeability of…
