Enter the magnetic flux and the area through which the flux is passing into the calculator to determine the magnetic flux density. This calculator helps in finding the flux density, also known as magnetic field strength or magnetic induction.

## Magnetic Flux Density Formula

The following formula is used to calculate the magnetic flux density.

B = \frac{Phi}{A}

Variables:

- B is the magnetic flux density (teslas, T)
- Φ is the magnetic flux (webers, Wb)
- A is the area through which the magnetic flux is passing (square meters, m²)

To calculate the magnetic flux density, divide the magnetic flux by the area through which the flux is passing.

## What is Magnetic Flux Density?

Magnetic flux density is a measure of the strength of a magnetic field over a given area. It is a vector quantity, which means it has both magnitude and direction. Magnetic flux density is commonly measured in teslas (T), and it is used in various applications such as electromagnets, electric motors, generators, and magnetic resonance imaging (MRI).

## How to Calculate Magnetic Flux Density?

The following steps outline how to calculate the Magnetic Flux Density.

- First, determine the magnetic flux (Φ) in webers (Wb).
- Next, determine the area (A) through which the magnetic flux is passing in square meters (m²).
- Next, gather the formula from above = B = Φ / A.
- Finally, calculate the Magnetic Flux Density (B) in teslas (T).
- After inserting the variables and calculating the result, check your answer with the calculator above.
