Transformers are one of the most important devices in electrical engineering and power systems. They enable efficient voltage conversion, energy transfer, and isolation in AC circuits. By understanding transformers, one can grasp the principles of electromagnetic induction, energy conservation, and power distribution across electrical networks. This post covers transformers in detail, including working principles, types,…

Electromagnetic induction is a fundamental principle in physics and electrical engineering. While Faraday’s Law explains how changing magnetic fields induce EMF, self-inductance and mutual inductance describe how circuits and coils interact with their own or neighboring magnetic fields. These concepts are critical for understanding transformers, inductors, electrical circuits, and energy storage in magnetic fields. This…

Introduction Lenz’s Law, electromagnetism ka ek bunyadi aur zaroori concept hai, jo magnetic fields aur electric currents ke darmiyan interaction ko samajhne me madad karta hai. Ye law Heinrich Lenz ne 1834 me propose kiya tha aur aaj bhi electrical engineering aur physics me ek bunyadi principle ke tor par use hota hai. Simplest terms…

Electromagnetic induction is a cornerstone of classical electromagnetism and forms the foundation of most modern electrical devices, from generators to transformers. Faraday’s Law of Electromagnetic Induction, formulated by Michael Faraday in 1831, describes how a changing magnetic field produces an electric field, linking electricity and magnetism in a profound way. This post explores Faraday’s Law…

Magnetism is a fundamental property of matter associated with moving charges and electron spins. The study of magnetic properties of materials is critical in physics, engineering, and technology. Understanding how materials respond to magnetic fields allows scientists and engineers to design devices such as transformers, magnetic storage devices, motors, and sensors. 1. Introduction to Magnetism…

Ampère’s Circuital Law is one of the cornerstone principles in electromagnetism. It provides a powerful relationship between electric currents and the magnetic fields they produce. Named after the French physicist André-Marie Ampère, this law is a direct result of experimental observations and forms the foundation of magnetic field analysis in many practical applications, including electromagnets,…

The Biot-Savart Law is one of the fundamental principles of electromagnetism, describing how electric currents generate magnetic fields. Named after Jean-Baptiste Biot and Félix Savart, who formulated it in 1820, this law is analogous to Coulomb’s law for electric charges. It forms the basis for understanding magnetic fields due to current-carrying conductors, whether straight wires,…

Electric currents and magnetic fields are intimately connected. When a current-carrying conductor is placed in a magnetic field, it experiences a force known as the magnetic force on a conductor. This phenomenon is fundamental to the operation of electric motors, generators, and numerous electromechanical devices. Understanding this concept is crucial for students, engineers, and anyone…
