Classification of forms of description of the physical fields

ABSTRACT
Gived a classification of forms of description of the physical fields in the following three criteria: by type of field-generating charge, by the form of the medium and by the size of the field. Terminology of classification fields on the basis of the form of the charge does not coincide with the existing in modern physics.

Physical fields are classified according to various criteria, but with a clear classification with established terminology in the literature were found. Nevertheless, the existing terminology allows to offer such a classification scheme. For example, the classification of the forms describing the physical field may be performed by three criteria:
1. by type of charge, forming physical field (shell the charged system),
2. by detailing the size of the field,
3. by type the medium, in which there is a physical field (field medium).

Classification of forms of description of the physical field by type of charge

On the type of field-generating field-generating charge depends the form of the description on the physical form, the name of the form and its laws. On this basis, and provided the first classification, shown in a table.

Preliminary notes to Table.
1. By black color are printed the titles of terms dictated by the need for unification of terminology.
2. By red color are printed recommended titles of field-generating charges.
In lines called field-generating charge black bold specified the form of description of the field corresponding to the field-generating charge.
3. By blue color are printed in parentheses exist in modern physics titles.

Comments on the table.

1. Fixed charges, in principle, do not, so all charges are moving (dynamic) with field. But within the chosen reference system may exist charges fixed relative to each other, which can be called static.

2. From the viewpoint of S.Kadyrov (2001) and V.Pakulin (2004) any field-generating charge is clot of self-rotated field. And where there is rotation, one should speak not only about the potential, but also about the vortex component of the physical field. Therefore central field is a mathematical abstraction, and can only be seen as a central component of the physical field. Practically the same value of the intensity of potential component of the total field is significantly larger than the value of the vortex component. Therefore, such a mathematical abstraction, as the central field, is useful in practical calculations.

3. Existing In modern physics titles of forms described the electromagnetic field associated with the names of the charges, and charges are historical titles. The term "magnetic charge" in physics tend not to apply because they believe it to be zero. However, in electrical engineering use the term "magnetic mass" with the meaning of contour that is streamlined by electric current. However, in an article about magnetic charge, it is shown that the magnetic charge as a physical quantity that exists in the form of current charge , and is a particular case of dynamic charge. And in an article about current charge, it is shown that the magnetic charge is a synonym for the current charge.

4. The term "magnetic field" extremely strongly associated with the history of electromagnetism. In our view, this term when ordering physical concepts would be appropriate to replace by the term "electrodynamic field". But it is almost impossible, and therefore the term "magnetic field" can be left predominantly to consider phenomena in substancy.

5. Classification of gravitational field similar the classification of an electric field. What in modern physics called gravitational field is actually only gravistatical field. But analogue of electrodynamic (magnetic) field generated by dynamic charge in a gravitation is the vortex component of the gravitational field created by the flow of heavy bodies (gravitational current). This vortex component rightly be called gravidynamic field. So it is called, for example, by V.Konovalov (2006). Earlier S.Kadyrov (2001) proposed a name for it "inertial field" and then J.Asanbaeva (2001) proposed a name for it "graviinertial field." O.Repchenko (2008) for the same purpose uses the term "gravimagnetic field."

Классификация физических полей и методология физики

В учебных пособиях электричество и магнетизм рассматриваются последовательно друг за другом. Это продиктовано современной методологией физики, которая придерживается исторического метода преподавания. Системный подход указывает на предпочтительность применения дедуктивного метода перед историческим методом при преподавании физики. В разделе “Систематизация и педагогика“ показана возможность иной последовательности изложения учебного материала по электромагнетизму, которую позволяет проведенная систематизация физических величин и понятий.

Следует заметить, что электромагнитное поле благодаря широким возможностям его экспериментального исследования служит, в соответствии с условием аналогий, прекрасной моделью для вывода обобщенных определяющих уравнений, касающихся характеристик и параметров любой формы описания физического поля. Эти обобщенные уравнения можно потом распространить на другие формы описания физического поля. Именно таким путем пошел С.Кадыров (2001), разрабатывая свою версию теории гравидинамики, как аналога электродинамики. На базе его выводов Дж.Асанбаева (2001) объединила систему уравнений электродинамики Дж.Максвелла и систему уравнений гравидинамики С.Кадырова в единую систему уравнений Максвелла-Кадырова.

В.Пакулин (2004, 2007) предложил модификацию уравнений Максвелла, позволяющую учитывать все особенности электромагнитного поля. Он показал, что все основные законы электродинамики и магнитодинамики являются вариантами решения модифицированных им уравнений Максвелла. Согласно условию адекватности модифицированные В.Пакулиным уравнения Максвелла могут быть распространены и на все формы гравитационного поля.

Classification of physical fields on the basis of the size

Irrespective of the physical nature the physical fields can be divided into:

1. Microscopic fields, created by individual charged particles,
2. Macroscopic fields - fields averaged over the physically infinitesimal volume.

Most often considered the macroscopic fields. Special significance this classification acquired in electromagnetism, where under makrocurrets are understood conduction currents and currents transport, and under microcurrents - molecular (circular) currents caused by the movement of electrons in atoms, molecules and ions. When ordering quantities and concepts conduction currents are included as a factor in current charges, and the currents transport - in moving charges. Current and moving charges are variants of dynamic charge. Molecular currents are special cases of current contour charges, formed by the conduction currents flowing in a closed contour.

Classification of physical fields on the medium

This classification is associated with a physical examination of the fields of the same nature in the different environments in contact with each other. Usually considered a substance in the environment, called the physical vacuum. In electromagnetism, when the substance (solid or liquid) is surrounded by a gaseous medium (eg air), so the characteristics of a substance different from the characteristics of gas, but the gas characteristics to equate the characteristics of the physical vacuum.

In general, such terminology is used:
1. The external field, then there is a field in the medium surrounding a substance, it is also called field of foreign charges,
2. The internal field, then there is a field inside the substance, it is also called field of fixed charges,
3. The true field, viewed as the sum of external and internal fields.
4. The field without regard the properties of the medium, ie fictitious field, devoid of characteristics of any medium.

The latter variant of field in the Nature no. But intensity of such fictitious field in physics called pure intensity. Pure intensity is useful in compiling generalized defining equations. Types of field intensities according to this classification are shown in a separate table.
