# Question: Why Is The Symbol For Magnetic Field B?

## What is the symbol of magnetic field intensity?

Two different vectors are in use to represent a magnetic field: one called magnetic flux density, or magnetic induction, is symbolized by B; the other, called the magnetic field strength, or magnetic field intensity, is symbolized by H..

## How magnetic field is created?

Magnetic fields are produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin.

## What causes a magnetic field?

The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in the Earth’s outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.

## What is B in magnetic field?

Flux density B is a response of the medium to the applied excitation H. The relationship is defined by the magnetic permeability μ, such that: B = μ ⋅ H. (T) Thus, B is related to the properties of the material and its relation to the applied excitation (e.g. electric current) can be highly non-linear.

## Why is the magnetic field called B?

It looks like Maxwell used B for first time to represent magnetic flux density.

## What is difference between B and H?

B is magnetic flux density, whereas H is magnetic field intensity.

## Where is magnetic field strongest?

the closer the lines, the stronger the magnetic field (so the magnetic field from a bar magnet is strongest closest to the poles) the lines have arrowheads to show the direction of the force exerted by a magnetic north pole.

## Is the Earth’s core magnetic?

The core of the Earth is also an electromagnet. Although the crust is solid, the core of the Earth is surrounded by a mixture of molten iron and nickle. The magnetic field of Earth is caused by currents of electricity that flow in the molten core.
