Electromagnetics deals with Electric and Magnetic fields. Biot-Savart’s Law is the basic governing law for the study of static magnetic fields. In this article lets us discuss it along with its applications in our EMT. The Statement The magnetic field …

Electric flux density or D is a common term in Electromagnetics particularly in the study of Electrostatics and Gauss’ Law. This article explains its significance along with the comparison with E. What is Electric Field Intensity (E)? Every charge posses …

Electric field arises because of the charge. We are well aware of its standard formulas. This article explains the standard procedure for deriving the expression for Electric Field Intensity due to distributed charge. The standard steps discussed over here could …

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 …
