## 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)

## Magnetic Flux Definition

A magnetic flux is defined as the total strength of the magnetic field that passes through any given area.

## Magnetic Flux Example

How to calculate magnetic flux?

**First, determine the magnetic field.**Measure the strength of the magnetic field.

**Next, determine the total area.**Calculate the total area the magnetic field is moving through.

**Next, determine the angle.**Calculate the angle between the magnetic field and the area.

**Finally, calculate the magnetic flux.**Calculate the magnetic flux using the formula above.

## FAQ

**What is magnetic flux?**

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 field is acting across.

**What is an electric field?**

An electric field is a field producing a force due to the flow of electrons.
