Definition

vector quantity given by

H = \frac{B}{μ_{0}} - M

where $B$ is magnetic flux density (magnetic flux density), $μ_{0}$ is the magnetic constant (magnetic constant), and $M$ is the magnetization (magnetization)

grandeur vectorielle donnée par

H = \frac{B}{μ_{0}} - M

où $B$ est l'induction magnétique (magnetic flux density), $μ_{0}$ est la constante magnétique (magnetic constant) et $M$ est l'aimantation (magnetization)

Notes

The magnetic field strength is related to the total current density $J_{tot}$ (total current density) via

r o t H = J_{tot}

The magnetic field strength, the magnetic flux density, and the magnetization depend on the position.

See IEC 60050-121,locality:item="121-11-56".
