# FAQ: What Does B Mean In Physics?

B = magnetic flux density.

## What is B in magnetic field?

The definition of H is H = B/μ − M, where B is the magnetic flux density, a measure of the actual magnetic field within a material considered as a concentration of magnetic field lines, or flux, per unit cross-sectional area; μ is the magnetic permeability; and M is the magnetization.

## What is difference between B and H?

The difference between B and H is that B is used for representing the magnetic flux density while H is used for representing the magnetic field intensity.

## What does Y mean in physics?

Cartesian y -axis basis unit vector. unitless. kinetic energy. joule (J) Boltzmann constant.

## What is B in flux?

Magnetic flux density(B) is defined as the force acting per unit current per unit length on a wire placed at right angles to the magnetic field. Units of B is Tesla (T) or Kgs−2A−1.

## Why is it called B field?

Most textbooks on electricity and magnetism distinguish the magnetic field H and the magnetic induction B. Yet, in practice physicists and chemists almost always call B the magnetic field, which is because the term “induction” suggests an induced magnetic moment.

## What is the difference between B and H in magnetic field?

B is the magnetic flux density and is unique to the material. Higher μc means more magnetic flux density under the same magnetic field. H is the magnetic field strength and is an absolute quantity.

## Can we see magnetic flux lines?

Solution: No, we cannot see magnetic flux lines as the “lines of magnetic flux” is purely an imaginary concept to understand the magnetic field clearly.

## What is magnetization formula?

Magnetization is a measure of the density of magnetism and may be calculated from the number of magnetic moments in a given volume. This may be shown as M = Nm/V where M is the magnetization, N is the quantity of the magnetic moment, m is its direction and V is the volume of the sample.

## What does D in physics stand for?

“d” means change in the limit that the change is infinitestimal. in your particular exapmle: really means “average” current because that’s total change in charge over total change in time: in fact it means., now when in the limit of very small change. ie.

## What is U in physics class 9?

u is initial velocity. v is the final velocity. a is acceleration. t is the time period.

## What does P stand for in physics electricity?

Electric power (P) is simply the product of current times voltage. Power has familiar units of watts. Since the SI unit for potential energy (PE) is the joule, power has units of joules per second, or watts. Thus, 1 A ⋅V= 1 W.

## What is B unit?

In SI units, B is measured in teslas (symbol: T). In Gaussian-cgs units, B is measured in gauss (symbol: G). (The conversion is 1 T = 10000 G.) One nanotesla is equivalent to 1 gamma (symbol: γ).

## What is the symbol of magnetic flux?

Magnetic flux is denoted by the Greek letter Phi and has the symbol Φ or ΦB. Fluxmeter is used to measure magnetic flux.

## What is SI unit of magnetic flux?

The SI unit of magnetic flux is the weber (Wb; in derived units, volt–seconds), and the CGS unit is the maxwell.
