BASIC ELECTROMAGNETISM What is Flux? Flux means an imaginary lines through which a physical quantity can travel. The word “Flux” is originated from the Latin Word ‘Fluxus’ that means flow. Isaac Newton first used this term as fluxion into differential calculus. In mathematics and physics flux is used as the basic and global word. Types of Flux Flux can be used in various concepts, such as Magnetic Flux It means the number magnetic field lines passing through a closed surface. Its SI unit is – Weber and in CGS is – Maxwell. It is denoted by φM. Electric Flux It means the number of electric field lines passing through a closed surface. Its SI unit is – volt meter. It is denoted as φE. Luminous Flux It means the line of transmitted visually sensible radiated energy per second. Its SI unit is Lumen (lm). Radiant Flux or Energy Flux It means the line of transmitted radiated energy per second from any energy source. Its SI unit is Watt. It is denoted as φV. Heat Flux It means the heat energy transfer through an elementary surface per second. Its SI unit is W/m2. It is denoted as Φq. Thank You for watching
