Question

if the magnetic flux passing through an area( A) taken perpendicular to the field then write the formula to find the magnetic flux density.​

Answer 1

Answer:

answer. answer: magnetic flux density is amount of magnetic flux through unit area taken perpendicular to direction of magnetic flux. flux density (b) is related to magnetic field (h) by b=μh.

Answer 2

Concept

The surface integral of the normal component of the magnetic field B across a surface represents magnetic flux through that surface.

Given

Magnetic field and area of the cross-section are perpendicular to one another.

To Find

Expression of magnetic flux density.

Solution

The mathematical expression for the magnetic flux is $\phi=BA cos\theta$ where, B is the magnetic field, A is the area of the cross-section and $\theta$ is the angle between B and A.

According to the question, $\theta=90^o$ so, the expression for the magnetic flux will be-

$\phi=BAcos(90)\\=0$

Hence, the magnetic flux is 0.
