This vCalc Magnetic Flux conversion equation converts the input measure of magnetic flux into other units of magnetic flux that you choose.  Just enter a value in the input units field and then select your chosen units for the output displayed.

Description:

A flux density of one Wb/m2 (one weber per square meter) is one tesla.

Inputs:

The units of flux supported by vCalc for conversion are:

• Wb - the weber;  Wb = (kg*m^2) / (s^2 * A) = V*s = T * m^2 = J/A

where V = volt, T = tesla, J = joule, m = meter, s = second, A = ampere

• Mx - the maxwell

Usage:

Magnetic flux through a surface is represented by the surface integral of the normal component of the magnetic field (B) passing through that surface.

Magnetic flux measures what force would be experienced by a moving charge at  a point in the magnetic field.

The magnetic flux through a surface in a simplified picture is proportional to the net number of field lines passing through that surface.  In more advanced physics illustrations, the field line analogy is dropped and the magnetic flux is more accurately described by the surface integral of the normal component of the magnetic field passing through a surface. If the magnetic field is constant, the magnetic flux passing through a surface of vector area A is:

Phi_B = vecB*vecA = B*S cos(theta) , where:

B is the magnitude of the magnetic field (the magnetic flux density having the unit of Wb/m2 (tesla) ), A is the area of the surface, and θ is the angle between the magnetic field lines and the normal (perpendicular) to A.1
