Electric flux is a measure of the electric field passing through a given surface. It provides insight into how much electric field penetrates or crosses a specific area. The concept is particularly useful in understanding the interaction between electric fields and surfaces, such as when studying Gauss’s Law or the behavior of charged particles. Definition: … Read more
electric field due to a dipole along the axial line To derive the electric field due to a dipole along the axial line, we can follow these steps: \(\displaystyle E_1 = \frac{1}{4\pi\epsilon_0}\frac{q}{(r-a)^2}\) The direction of \(E_1\) is along \(\vec{OP}\), where \(O\) is the origin. \(\displaystyle E_2 = \frac{1}{4\pi\epsilon_0}\frac{q}{(r+a)^2}\) The direction of \(E_2\) is along \(\vec{OP’}\), … Read more
Introduction An electric dipole is a system of two equal and opposite electric charges that are separated by a small distance. An electric dipole has a property called the electric dipole moment, which is a vector that measures the magnitude and direction of the charge separation. The charges, one positive and one negative, create a … Read more
What is an Electric Field Line? Electric field lines were, introduced by Michael Faraday in the 19th century, electric field lines provide a unique and intuitive way to represent the distribution, strength, and direction of the electric field surrounding charged objects. The concept of electric field lines starts with the recognition that charged particles influence … Read more
The idea of an electric field emerged in the mid-19th century, thanks to the pioneering work of Michael Faraday. Faraday introduced the concept to explain how a charged object, like a point charge, can influence the space around it without any physical contact. A point charge is an idealized small object with a specific amount … Read more
The story of the electric field begins in the early 19th century with a brilliant scientist named Michael Faraday. Faraday was fascinated by electricity and magnetism, which were relatively new and mysterious forces at the time. He conducted numerous experiments to understand how electric charges interact with each other. Faraday proposed that charges do not … Read more
The story of Coulomb’s Law begins with a French physicist named Charles-Augustin de Coulomb. In 1785, Coulomb made a groundbreaking discovery that would become a cornerstone of electrostatics. He was interested in understanding the forces that charged objects exert on each other. Coulomb conducted a series of experiments using a torsion balance, which is a … Read more
