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.

3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
report of one of the following types:
• type 1, when the required support cannot be obtained for the publication of an
International Standard, despite repeated efforts;
• type 2, when the subject is still under technical development or where for any other
reason there is the future but no immediate possibility of an agreement on an International
Standard;
• type 3, when a technical committee has collected data of a different kind from that
which is normally published as an International Standard, for example "state of the art".
Technical reports of types 1 and 2 are subject to review within three years of publication to
decide whether they can be transformed into International Standards. Technical reports of
type 3 do not necessarily have to be reviewed until the data they provide are considered to be
no longer valid or useful.
IEC 61000-2-7, which is a technical report of type 3, has been prepared by subcommittee 77A:
Low frequency phenomena, of IEC technical committee 77: Electromagnetic Compatibility.

ELECTROMAGNETIC COMPATIBILITY (EMC) –
Part 2: Environment –
Section 7: Low frequency magnetic fields
in various environments
1 Scope
Interest in magnetic fields has been stimulated in recent years by concern over the
physiological effects they may have on humans and animals and the deleterious effects they
have on the performance of some electrical equipment, particularly video display units.
Investigations have yielded results which are presented in this report as reference values.
Note 1 – The European Union EMC Directive has prompted magnetic field measurements, particularly in respect of
the commercial office environments associated with supply authority substations and electrical distribution systems
within buildings. Supply authorities have sponsored most of the work and the results are generally within the
frequency range of 50 Hz to 2 kHz, and presented as r.m.s. values. There is, however, a need to have some
knowledge about d.c. fields and the fields up to 150 kHz as they may interfere with some types of equipment.
Note 2 – Most of the magnetic field data in this report is associated with sinusoidal current sources and r.m.s.
values may be assumed unless otherwise stated.
Power supply systems operating at voltages less than or equal to 1 000 V are designated low-voltage, those above
1 000 V and up to 35 kV are designated medium-voltage, and those in excess of 35 kV are designated high-voltage.
2 Normative reference
The following normative document contains provisions which, through reference in this text,
constitute provisions of this technical report. At the time of publication, the edition indicated
was valid. All normative documents are subject to revision, and parties to agreements based
on this technical report are encouraged to investigate the possibility of applying the most recent
edition of the normative document indicated below. Members of IEC and ISO maintain registers
of currently valid International Standards.
IEC 60050(161):1990, International Electrotechnical Vocabulary (IEV) – Chapter 161: Electro-
magnetic compatibility.
3 Units
Magnetic field values in this report are either expressed in field strengths of amperes per
metre, A/m, or in flux densities of microtesla, μT. Where the older flux density unit of
milligauss, mG, has appeared in reference documents it has been converted to μT by the
following relationship:
1 μT = 10 mG ≈ 0,796 A/m
The following units are applied in the present report:
Magnetic field strength: H in A/m
Magnetic flux density: B = μ × H in T (Tesla)
–6
whereby the permeability μ =μ × μ and μ = 1,256⋅10 (Wb/Am)
r 0 0
in air the relative permeability μ = 1 and B (μT) = 1,256 H (A/m)

NOTE – 1 T = 1 Wb/m = 10 G and B = 1,256·10 G (in air)

IEC  1 527/97
An alternating current produces an alternating magnetic field, and in the case of a multi-phase
cable or overhead line, the alternating magnetic field rotates as it results from the vector sum
of the fields produced by individual phase currents.
An alternating magnetic field will induce an electromotive force in any electrical conductor to
which it is exposed. This effect is utilised by meters which have search coils. Such meters are
in common use.
Other types of meter used for low frequency measurements utilise the Hall effect. These
meters are not so good for measuring the fields from environmental sources, but they are very
useful when measuring points in space and static magnetic fields.
