Magnetic Flux Formula
The following equation can be used to calculate a magnetic flux.
F = B * A * cos ( a )
- Where F is the magnetic flux (webers)
- B is the magnetic field (teslas)
- A is the area (m^2)
- a is the angle between the magnetic field and area (use 90 if no angle given)
To calculate a magnetic flux, multiply the magnetic field strength by the area, then multiply by the cosine of the angle between the field and area.
Magnetic Flux Definition
A magnetic flux is defined as the total strength of the magnetic field that passes through any given area.

FAQ
Magnetic flux is a measure of the total magnetic field that passes through an area. In other words, it’s the strength of the field times the total area that the field is acting across.
An electric field is a field producing a force due to the flow of electrons.
