Question

What is the use of introducing the ideas of magnetic flux and magenetic flux density

Answer 1

Answer:

it just tells us about the number of magnetic field lines passing through a surface

Answer 2

Given that,

Magnetic flux density and magnetic flux

Magnetic flux density :

Magnetic flux density is equal to the flux divided by the area. It is represents by B and its unit is tesla.

In mathematically,

$B=\dfrac{\phi}{A}$

Where, B = magnetic flux density

$\phi$ = flux

A = Area

Magnetic flux :

The number of magnetic field lines passing through a closed surface.

Magnetic flux is equal to the product of magnetic field and area. Area is perpendicular to the magnetic field.

The unit of magnetic flux is weber.

In mathematically,

$\phi=BA$

Where, B = magnetic field

A = area

$\phi$ = flux

Hence, This is required answer.
