Question

What is the formula for flux density?

Answer 1

Flux density is just the total flux divided by the cross-sectional area of the portion through which it moves. Electric flux density is described as “the amount of flux moving through the unit surface area in the place imagined at a right angle to the electric field direction. Magnetic flux density is the line number of forces moving through a unit area. Flux density is related to field strength through permeability.

Complete step-by-step solution:
When we talk about flux density formulas, we have to be a little specific because there are usually two flux density formulas. It involves Magnetic flux density and Electric Flux density. We will see both.
Flux density,
$FD = \dfrac{F}{A}$
where, F is the flux,
A is the cross-sectional area.
Electric flux density measures the strength of an electric field produced by a free electric charge, corresponding to the amount of electric lines of force moving through a given area. Electric flux density is the quantity of flux crossing through a defined area perpendicular to the flux's direction.
Magnetic flux density is a vector quantity estimating the strength and direction of the magnetic field about a magnet or an electric current. Magnetic flux density is equivalent to magnetic field strength times the magnetic permeability in the field's region. The magnetic flux density is the quantity of lines of force moving through a unit area of material, B. Tesla is the unit of magnetic induction.

Note: Flux density is the amount of the field passing through a unit area. These ideas are essential in electromagnetics, power, physics, electrical engineering, and many more departments—flux density unit - an estimate of the flux amount per unit of cross-sectional area electromagnetic unit.
