Magnetic flux is defined as the number of magnetic field lines passing through a given closed surface. It provides the measurement of the total magnetic field that passes through a given surface area.
In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or ΦB. The SI unit of magnetic flux is the weber (Wb; in derived units, volt–seconds), and the CGS unit is the maxwell. [1]
magnetic flux: A measure of the strength of a magnetic field in a given area. induction: The generation of an electric current by a varying magnetic field. Faraday’s law of induction: A basic law of electromagnetism that predicts how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF).
What is Magnetic Flux. Magnets and electromagnets produce a magnetic field represented by imaginary lines known as magnetic field lines or magnetic lines of force. Magnetic flux is the number of lines passing through a given area, whether in air or vacuum or inside a magnetic material.

To put in simple terms, magnetic flux is the amount of magnetic field going through a given area in a singular instant of time. Whether the area is non uniform, or if the magnetic field isn't constant, you can use the magnetic flux formula to calculate the number of Teslas in the given area.
Definition of Magnetic Flux: Magnetic flux, denoted by the symbol Φ (phi), is a measure of the total magnetic field passing through a surface perpendicular to that field. It is analogous to the concept of electric flux in electrostatics.
Magnetic flux is a measure of the quantity of magnetism, taking into account the strength and extent of a magnetic field. It represents the total magnetic field passing through a given area and is crucial for understanding electromagnetic phenomena such as induction and magnetic forces.
The most basic definition is the magnetic flux through a plane figure due to a uniform magnetic field. Consider a plane region of area, A A, and choose a unit vector, \mathbf {n} n, perpendicular to the surface. For convenience an area vector, \mathbf {A} A, is defined by \mathbf {A} A = = A A \mathbf {n} n.
More formally it is defined as: Advertisement. Φ B = B ⋅ A = B A cos. . θ. where θ is the angle between the magnetic field B and the perpendicular to A at the defined region. • The magnetic field B, or the magnetic flux density per unit area , is measured in tesla (T) in SI units, while A is the. area the field is passing through in m 2.
