What is the energy density of a magnetic field?

H as the 2 energy density, that is, energy per unit volume stored locally in the magnetic field. current changes the magnetization is volume integral of ∫ H ′ dB ′ . However, this energy is not all recovered when the B returns to its initial value because the path of integration is different.

Is there a plausibility argument for storage of energy in magnetic fields?

This is a plausibility argument for the storage of energy in static or quasi-static magnetic fields. The results are exact but the general derivation is more complex than this. Consider a ring of rectangular cross section of a highly permeable material.

What is the enhancement factor of spectral stored energy density?

First we describe how the stored energy is distributed in the space surrounding the sphere. We define the enhancement factor of spectral stored energy density with respect to the ideal blackbody energy density uB as (55) Υ ˜ = ( Υ E − Υ ∞) + ( Υ H − Υ ∞).

Is energy density a complex exponential representation?

No, energy density is generally represented by E, not a complex exponential. The energy density of an electromagnetic wave is proportional to the square of the amplitude of the electric (or magnetic) field.

How do you find the energy density of an electromagnetic wave?

The energy density of an electromagnetic wave is proportional to the square of the amplitude of the electric (or magnetic) field. This is represented by the equation B2 ! !t)ez = uEMcez, where S is the energy density multiplied by the velocity of the wave cez.

What is the energy density of an electromagnetic wave proportional to?

The energy density of an electromagnetic wave is proportional to the square of the amplitude of the electric (or magnetic) eld.
