Question

Magnetic flux density isselect one:a. B=(permivitivty) x hb. B=(permeability) x hc. B=(permeability) x ed. B=(permivitivty) x e

Answer 1

answer : magnetic flux = $\mu\bar{H}$

explanation : magnetic flux is dot product of magnetic field intensity and area vector.

e.g., $\phi=\vec{B}.\vec{A}$

we know, $B=\mu\bar{H}$

where $\bar{H}$ is magnet field intensity in a medium.

so, $\bar{B}=\mu\bar{H}.A$

and magnetic flux density is the ratio magnetic flux to the cross sectional area.

e.g., $\bar{B}=\frac{\mu\bar{H}.A}{A}$

or, $\bar{B}=\mu\bar{H}$

hence, magnetic flux density = (permeability) × H
