Discovery of Electromagnetism
The discovery of electromagnetism in the 19th century began with Hans Christian Ørsted’s observation in 1820 of a compass needle’s deflection near an electric current. André-Marie Ampère formulated mathematical equations linking electric currents and magnetic fields, while Michael Faraday discovered electromagnetic induction in 1831. Faraday’s work paved the way for electrical generators and transformers. James Clerk Maxwell later unified these findings into Maxwell’s equations in the 1860s, predicting electromagnetic waves. This synthesis formed the foundation of modern electromagnetism, revolutionizing physics and paving the way for technologies reliant on electricity and magnetism.
Electromagnetism
Electromagnetism is a fundamental branch of physics that explores the interaction between electric fields and magnetic fields. It is one of the four fundamental forces of nature, alongside gravity, the weak nuclear force, and the strong nuclear force. This field of study not only talks about the nature of electric charges and magnetic moments but also studies the behavior of electromagnetic waves, which include visible light, radio waves, and X-rays.
Electromagnetism has applications in both theoretical and applied physics. It forms the basis for modern electrical and electronic technologies, including the generation and distribution of electric power, telecommunications, and medical imaging techniques like MRI.
In this article, we will read in detail about electromagnetism, its discovery, examples, laws related to it, applications and other facts related to it.
