Electric field intensity is a very common term in Electromagnetism representing the strength of the Electric field. This article elaborates its definition in simple words. What is Electric Field? A field is a general term analogous to function in mathematics. …

Charge density is the charge distributed per unit length, surface or volume. If charge is distributed over the body then there may be three possible distributions i.e. over the line, over the surface and within the volume. This arises the …

French physicist, Charles-Augustin de Coulomb, has observed that there is an interaction or a force between two charged particles. He formulated this force as an electrostatic force and known as Coulomb’s Law. The statement of Coulomb’s Law Coulomb’s Law states …

Curl of the vector field is an important operation in the study of Electromagnetics and we are well aware with its formulas in all the coordinate systems. Generally, we are familiar with the derivation of the Curl formula in Cartesian …

Each coordinate system is uniquely represented with a set of unit vectors. You may think them as the constants and their derivatives be zero. But derivatives of the unit vectors are not zero all the time. This article discusses the …

Divergence of the vector field is an important operation in the study of Electromagnetics and we are well aware with its formulas in all the coordinate systems. Generally, we are familiar with the derivation of the Divergence formula in Cartesian …

The Del Operator is useful in vector differentiation particularly for finding Gradient, Divergence, Curl etc. Let us obtain the expression for the Spherical Del Operator starting from Cartesian. What is Del Operator? It is significant in vector differentiation for finding …

The del operator is useful for finding Gradient, Divergence, Curl and Laplacian. Let us discuss how can we get the cylindrical Del operator from its Cartesian formula. What is the Del Operator? It is a vector differentiation tool. It is …

Del operator is a vector differential operator which has a significant role in Electromagnetics for finding Gradient, Divergence, Curl and Laplacian. This article discusses its definition and significance. The Del Operator Definition for Cartesian Coordinates In very simple words, it …

Scalar field and Vector field are basic concepts whose proper understanding is necessary for the study of Electromagnetics. This article explains their definitions and difference. What do we mean by field? In general, the word “Field” is synonym for “Function” …
