Quantities and units - Part 6: Electromagnetism

IEC 80000-6:2022 gives names, symbols, and definitions for quantities and units of electromagnetism. Where appropriate, conversion factors are also given. International Standard IEC 80000-6 has been prepared by IEC technical committee 25: Quantities and units, and their letter symbols in close cooperation with ISO/TC 12, Quantities and units.
This standard is based on classical electromagnetism, i.e. mainly Maxwell’s equations. No reference is made to quantum field theories.
IEC 80000-6:2022 cancels and replaces the first edition published in 2008. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
1) With the new definitions in SI, some previously exact values for quantities now must be determined experimentally while other quantities are given as exact values;
2) Item 6-2.2, elementary charge added;
3) Item 6-11.4, induced voltage, added;
4) Index of entries added;
5) Editorial alignment to other parts of the IEC and ISO 80000 series.

Grandeurs et unités - Partie 6: Electromagnétisme

L'IEC 80000-6:2022 donne des noms, des symboles et des définitions pour les grandeurs et les unités d'électromagnétisme. Le cas échéant, des facteurs de conversion sont également indiqués.
Cette norme est basée sur l'électromagnétisme classique, c'est-à-dire principalement les équations de Maxwell. Aucune référence n'est faite aux théories quantiques des champs.
L’IEC 80000-6 a été établie par le comité d'études 25 de l’IEC: Grandeurs et unités, et leurs symboles littéraux, en coopération étroite avec l'ISO/TC 12, Grandeurs et unités. Il s'agit d'une Norme internationale.
Cette deuxième édition de l’IEC 80000-6 annule et remplace la première édition parue en 2008. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
1) avec les nouvelles définitions du SI, certaines valeurs auparavant exactes pour des grandeurs doivent maintenant être déterminées de manière expérimentale, tandis que d'autres grandeurs sont données comme des valeurs exactes;
2) ajout de l’article 6-2.2, charge élémentaire;
3) ajout de l’article 6-11.4, tension induite;
4) ajout d’un index des entrées;
5) alignement rédactionnel sur d'autres parties des séries IEC et ISO 80000.

QUANTITIES AND UNITS –
Part 6: Electromagnetism
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 80000-6 has been prepared by IEC technical committee 25: Quantities and units, and their
letter symbols in close cooperation with ISO/TC 12, Quantities and units. It is an International
Standard.
This second edition of IEC 80000-6 cancels and replaces the first edition published in 2008.
This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) With the new definitions in SI, some previously exact values for quantities now must be
determined experimentally while other quantities are given as exact values;
b) Item 6-2.2, elementary charge added;
c) Item 6-11.4, induced voltage, added;
d) Index of entries added;
e) Editorial alignment to other parts of the IEC and ISO 80000 series.

INTRODUCTION
0.1 Tables of quantities
The names in English of the most important quantities within the field of this document are given
together with their symbols and, in most cases, their definitions. The definitions are given for
identification of the quantities in the International System of Quantities (ISQ), listed in Table 1;
they are not intended to be complete.
The scalar, vectorial or tensorial character of quantities is pointed out, especially when this is
needed for the definitions.
In most cases, only one name and only one symbol for t
