Table of Contents Introduction Nature and Definition of Electromagnetics Fundamental Vector Fields in Electromagnetics Static vs Time-Varying Fields Universal Constants in Electromagnetic Theory Maxwell's Equations : The core of Electromagnetics Conclusion Introduction James Clerk Maxwell gave mathematical shape to electromagnetic fields in a systematic manner. Electromagnetics talks about the interaction of electricity and magnetism and is the basic to everything electric and magnetic. Understanding electromagnetic means understanding the scalar and vector field associated with it. Before understanding the concept of electromagnetic one should have some understanding of scalar and vector fields in different coordinate systems. The concept of line integral, surface integral and volume integral are important along with the concept of gradient, divergence and curl.

  Electric Charge and Material Science   Fundamentals  “From Subatomic Particles to Semiconductors” 🌟 1. What Is Electric Charge? Electric charge is one of the most fundamental properties of matter. It is responsible for creating electric and magnetic fields , which in turn produce electromagnetic force —one of the four fundamental forces of nature (along with gravity, strong nuclear, and weak nuclear forces). Every object in the universe is made up of atoms, and these atoms consist of subatomic particles: Protons (positively charged) Electrons (negatively charged) Neutrons (no charge) The net electric charge of an object determines how it interacts with other charged particles. If an object has more electrons than protons, it is negatively charged . If it has more protons, it is positively charged . If both are equal, it is neutral . 🔹 2. Types of Electric Charge There are two types of electric charge : 🧲 Positive Charge: Carried by pr...
