The formula to calculate the flux density is:
\[ FD = \frac{\Phi}{A} \]
Where:
Let's say the total flux (\( \Phi \)) is 5 Webers and the total area (\( A \)) is 2 square meters. Using the formula:
\[ FD = \frac{5}{2} \]
We get:
\[ FD = 2.5 \text{ Wb/m²} \]
So, the flux density (\( FD \)) is 2.5 Wb/m².
Flux density is defined as the total flux per unit area generated from a magnetic field. It is a measure of the strength of the magnetic field over a given area and is typically measured in Webers per square meter (Wb/m²).
Definition: Flux density is the measure of the number of magnetic field lines passing through a given area.
Formula: \( B = \frac{\Phi}{A} \)
Example: \( B = \frac{0.5}{0.1} \)
Definition: Power flux density is the measure of power per unit area.
Formula: \( S = \frac{P}{A} \)
Example: \( S = \frac{100}{10} \)
Definition: Electric flux density is the measure of electric flux passing through a unit area.
Formula: \( D = \epsilon E \)
Example: \( D = 8.85 \times 10^{-12} \cdot 100 \)
Definition: Maximum flux density is the highest value of flux density in a given area.
Formula: \( B_{max} = \frac{\Phi_{max}}{A} \)
Example: \( B_{max} = \frac{1}{0.2} \)
