In more advanced physics, the field line analogy is dropped and the magnetic flux is properly defined as the surface integral of the normal component of the magnetic field passing through a surface. The density of the lines indicates the magnitude of the magnetic field. Although most of the magnetic flux observed on the sun originates in the low-latitude sunspot belts, this flux is gradually dispersed over a much wider. The maximum exposure level at the frequency of interest, in magnetic flux density (unit microT), for a specific population. The formula gives the magnetic flux B B.AB. continuous lines of force or magnetic flux that emerge from north-seeking magnetic poles and enter south-seeking magnetic poles.
The magnetic flux is the net number of field lines passing through that surface that is, the number passing through in one direction minus the number passing through in the other direction (see below for deciding in which direction the field lines carry a positive sign and in which they carry a negative sign). The magnetic flux is a tool to describe the effect of the magnetic force on anything under the influence of a magnetic field thus particular area must be chosen for the magnetic flux.
The magnetic flux through some surface, in this simplified picture, is proportional to the number of field lines passing through that surface (in some contexts, the flux may be defined to be precisely the number of field lines passing through that surface although technically misleading, this distinction is not important). The SI unit of magnetic flux is Weber (Wb), indicated by the letter B, where B represents the magnetic field. The density and strength of the magnetic and electric field depend upon the number of flux lines penetrating through the unit area of the conductor. Magnetic flux is the imaginary line which visualizes the strength of the magnetic field generated in the wire and the direction of propagation of the field lines. There are three ways to change the magnetic flux through a loop. Magnetic flux refers to the total number of magnetic field lines penetrating any surface placed perpendicular to the magnetic field. The flux is the imaginary lines formed by the magnetic or electric field and are always close loops in the field.

The SI unit for magnetic flux is the weber (Wb). B n B.A cos Where, n represents the number of wires employed to generate flux. Therefore, the magnetic flux density is defined as the magnetic flux passing normally (at 90°) per unit area and is denoted by B, i.e. The formula gives the magnetic flux due to a bunch of wires. The magnetic flux density is the measure of amount of magnetic flux in each square meter of the magnetic field. So the magnetic flux from the bunch of wire is more.
Changing magnetic flux creates an electromotive force, and if near a wire makes electric current flow through an electric circuit. magnitude equal to the area of a surface, and a direction perpendicular to the plane of the surface. The magnetic flux penetrated from a bunch of wires is also due to the magnetic field contributed by each wire.
Since a vector field is quite difficult to visualize at first, in elementary physics one may instead visualize this field with field lines. Students know magnetic materials and electric currents (moving electric charges) are. Magnetic flux is the amount of magnetic field perpendicular to a surface, passing through that surface. The magnetic interaction is described in terms of a vector field, where each point in space is associated with a vector that determines what force a moving charge would experience at that point (see Lorentz force). \( \newcommand\) may alternatively be described as having units of Wb/m\(^2\), and 1 Wb/m\(^2\) \(=\) 1 T.Each point on a surface is associated with a direction, called the surface normal the magnetic flux through a point is then the component of the magnetic field along this direction. 22 B, magnetic flux density, is measured in tesla (in SI base units: kilogram per second2 per ampere), : 21 which is equivalent to newton per meter per.
