The dot product of the area and the magnetic field passing through it. Graphically, it is a measure of the number and length of magnetic field lines passing through that area. It is measured in Webers (Wb).

the flow of energy, usually measured in Weber per square meter

The measurement of magnetic flux inside the air gap.

One weber is the magnetic flux which, linking (threading through) a circuit of one turn, induces in that circuit a voltage of one volt as the flux is reduced to zero at a uniform rate in one second.

the magnetic flux (webers) threading a given area is the integral of the magnetic induction over the area

Is a contrived but measurable concept that has evolved in an attempt to describe the “flow” of a magnetic field. When the magnetic induction, B, is uniformly distributed and is normal to the area, A, the flux, Ø = BA.

the product of the magnitude of the magnetic field, the magnitude of surface area, and the cosine of the angel between the direction of the field and the normal to the surface (see equation 19.2)

The total magnetic induction over a given area. When the magnetic induction, B, is uniformly distributed over an area A, Magnetic Flux = BA.

The product of the average magnetic field times the perpendicular area that it penetrates.

Expressed in webers, it is the product of the average normal component of the magnetic intensity over a surface and the area of that surface.

The total magnetic induction over a given area. When the magnetic induction, B, is uniformly disributed over an area A, Ã˜=BA. The general equation is Ã˜=B. dA.

The total magnetic induction over a certain area.

Magnetic flux, represented by the Greek letter phi, is a measure of quantity of magnetism, taking account of the strength and the extent of a magnetic field. The SI unit of magnetic flux is the weber (in derived units: volt-seconds), and the unit of magnetic flux density is the weber per square meter, or tesla.
