w

Definition

scalar quantity given by the sum of scalar products:

w = (1 / 2) (E \cdot D + B \cdot H)

where $E$ is electric field strength (electric field strength), $D$ is electric flux density (electric flux density), $B$ is magnetic flux density (magnetic flux density), and $H$ is magnetic field strength (magnetic field strength)

grandeur scalaire donnée par la somme des produits scalaires:

w = (1 / 2) (E \cdot D + B \cdot H)

où $E$ est le champ électrique (electric field strength), $D$ est l'induction électrique (electric flux density), $B$ est l'induction magnétique (magnetic flux density) et $H$ est le champ magnétique (magnetic field strength)

Notes

Electromagnetic energy is a special kind of energy (ISO 80000-5: Thermodynamics). The electromagnetic energy density depends on position.

See IEC 60050-121,locality:item="121-11-65".
