2.4: Electric Flux Density

electric flux density; Electric flux density, assigned the symbol ({bf D}), is an alternative to electric field intensity (({bf E})) as a way to quantify an electric field. This alternative description offers some actionable insight, as we shall point out at the end of this section. First, what is electric flux density?

Flux vs. Flux Density

Flux density, also known as magnetic flux density or magnetic field strength, is a vector quantity that represents the strength and direction of a magnetic field at a specific point in space. It is denoted by the symbol B and is measured in units of Tesla (T) or Gauss (G).

What is the relation between magnetic flux density (B) and …

Magnetic field strength or field intensity (H) is the amount of magnetising force.. Magnetic flux density (B) is the amount of magnetic force induced on the given body due to the magnetising force H.. The relation between B and H is, B = μH. Where, μ is the relative permeability. Permeability is the measure of the ability of a material to support the formation of …

Energy in a Magnetic Field

The magnetic field strength, H is defined as: H = B/µ 0 Where B is the magnetic flux density, ... We can also calculate the energy density (energy per m 3) in a uniform field of a coil, or solenoid, using its Magnetic Field Strength (B), as the stronger the surrounding field, the more energy it stores. The energy density per unit volume of the ...

Magnetic field strength | Definition, Formula, & Units

magnetic field strength, the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself. It is expressed as the vector H and is measured in units of amperes per metre. 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 ...
