Faraday Cage

Introduction A Faraday Cage, named after the English scientist Michael Faraday, who invented it in 1836, is a shielded enclosure used to block electric fields. The cage operates on the principle of electrostatic induction and provides protection against electric fields by redistributing charge. The Principle of the Faraday Cage The underlying concept of a Faraday Cage can be understood with…

Maxwell's Equations

Introduction Maxwell’s equations are a set of four differential equations that form the foundation of classical electrodynamics, classical optics, and electric circuits. These four equations describe how electric and magnetic fields interact. They were derived by James Clerk Maxwell in the 19th century. The Four Equations Gauss’s Law for Electricity: This law states that the electric flux…

Chapter 4: Gauss' Law

4.1 Introduction to Gauss’ Law Gauss’ Law is a fundamental principle in electromagnetism that relates the net electric flux through a closed surface to the total charge enclosed by that surface. This law helps simplify the calculation of electric fields in situations with symmetry and is crucial in understanding the behavior of electric fields around various charge distributions. 4.2 Statement…

Chapter 3: Electric Flux

3.1 Introduction to Electric Flux Electric flux is a measure of the electric field passing through a given surface. It helps us understand how the electric field interacts with objects and how charges distribute themselves on the surfaces of objects. In this chapter, we will discuss the concept of electric flux in more detail and introduce its applications. 3.2 Calculating Electric Flux As…

Gauss's Law

Gauss’s Law is a fundamental principle in the field of electromagnetism, specifically related to electric fields and electric charges. It is one of the four Maxwell’s equations that describe the behavior of electric and magnetic fields in various contexts. Gauss’s Law provides a relationship between the electric field produced by a distribution of electric charges and the total charge enclosed by…

The relativistic form of Maxwell’s equation in Geometric Algebra is

\begin{equation}\label{eqn:maxwellStokes:20} \grad F = \inv{c \epsilon_0} J, \end{equation}

where \( \grad = \gamma^\mu \partial_\mu \) is the spacetime gradient, and \( J = (c\rho, \BJ) = J^\mu \gamma_\mu \) is the four (vector) current density. The pseudoscalar for the…

The integral forms of Maxwell’s equations can be used to derive relations for the tangential and normal field components to the sources. These relations were mentioned in class. It’s a little late, but lets go over the derivation. This isn’t all review from first year electromagnetism since we are now using a magnetic source modifications…

Maxwell’s Equations – Differential form of Gauss’s Law (Part 2)

Maxwell’s Equations – Differential form of Gauss’s Law (Part 2)

This is Part two of my 8 four part series on Maxwell Equations

In my previous article I discussed about Integral form of Gauss’s Law which is one of the Maxwell’s Equations. Now in this article I’ll discuss about Differential form of the Gauss’s Law. The integral form of Gauss’s law for electric fields relates the electric flux over a surface to the charge enclosed by that surface.…
