Question

Magnetic field intensity and magnetic flux density

Answer 1

Density is the ratio of anything upon its dimension through which it is spread up,

Now we know that flux is the dot product of magnetic field(B) and vector area(A),

Flux = B.A

For angle = 0°

Flux = BA

Flux/A =B (keep it in mind).

Now by the knowledge of first 3 lines,

Density = anything/ dimension

For flux density:

Flux density = Flux / area

Note: as flux is the count of the magnetic lines that are cut normally by coil or something, so the dimension of it will be the area through which it is spread up.

Hence it shows that magnetic field and flux Density are the same

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.

In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or ΦB. The SI unit of magnetic flux is the weber, and the CGS unit is the maxwell.
