NCERT notes Class 12 Physics Chapter 6 Electromagnetic Induction.
The phenomenon of producing an induced electromotive force due to changes in the magnetic flux associated with a closed circuit is known as electromagnetic induction. This electro-motive force is known as the induced electromotive force and the current that flows in the closed circuit is called the induced current.
If is the angle between the field's direction and the area's normal, then The magnetic flux ∅ linked with a surface held in a magnetic field B is defined as the number of magnetic lines of force crossing a closed area. The magnetic flux is the difference between the number of field lines going through a surface in one direction and the number passing through it in the other direction. The number of field lines determines the magnetic flux through a surface that flows through it the flux can be specifically defined as the number of field lines that pass through it. Because a vector field is difficult to interpret at first, field lines would be used to describe it in fundamental physics. The magnetic interaction is characterized as a vector field, in which each point in space is designated, a vector that indicates the force that a moving charge will encounter at that position. The SI unit of magnetic flux is Weber (Wb), while Maxwell is the CGS unit. It is commonly indicated by the symbol ∅ or ∅ B. In physics, generally electromagnetic induction, the magnetic flux throughout the surface integration of the normal component of the magnetic field B over a surface is the magnetic flux throughout that surface. It's a valuable tool for identifying the effects of magnetic force on things in a particular location. The overall magnetic field that traverses across a specific area is determined by magnetic flux. Magnetic Flux definition and Magnetic flux, meaning: Magnetic flux refers to the total number of magnetic field lines penetrating any surface placed perpendicular to the magnetic field. While Gauss Law detains all situations, it is only beneficial for “in hand” calculations when high degrees of symmetry exist in the electric field. The E in the Gauss-Law equation is affected by charges which lie outside a closed surface. If the electric flux isn’t affected by charges which aren’t within a closed surface. The electric flux over a surface A is given by a surface integral Gauss Law is known as Gauss Flux Theorem, and it is a law that relates the distribution of charge (electric) to the produced electric field. The net outward normal electric flux through any closed surface is proportional to the electric charge enclosed in a closed surface. Where d φ E is an electric flux for a non-uniform electric field. Non-Uniform Electric Field: The flux d Ф E through a small surface area dA is Is the angle between the electric field lines and normal to A. The formula of Electric Flux: The Electric Flux passing through the surface of vector area A is
