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.
