Question

What is flux density formula?

Answer 1

1. Magnetic flux density at a point is the number of magnetic lines of force passing through the unit area around the point in the normal direction.
2. Magnetic flux density is equal to the magnetic field strength times the absolute permeability of the region where the field exists.
3. Magnetic flux density formula, $B=\mu H$ where, $B$ is the magnetic flux density, $\mu$ is the magnetic permeability, $H$ is the magnetic field strength
4. Electric flux density at a point is the number of electric lines of force passing through the unit area around the point in the normal direction.
5. Electric flux density is equal to the electric field strength times the absolute permittivity of the region where the field exists.
6. Electric flux density formula, $D=\epsilon E$ where, $D$ is the electric flux density, $\epsilon$ is the electric permittivity, $E$is the electric field strength
