Magnetic field

Pr kamikaze we call such a body, in which electrons or ions can move freely. Guides called the body, in which electrons or ions can move freely. They are divided into two groups. The first among all the metals as a body whose atoms have the characteristic property that easily lose electrons circulating on the outer orbits of atoms. This is explained by the ability of metals to the current leadership - are the bearers of its electrons. The flow of free electrons in metals is called electric current. The second group of guides are electrolytes. In the current electrolytic phenomenon occurs as a result of ion movement, IE particles endowed with electric loads. Laden with positive ions (cations) flow to the cathode, and laden with negative ions (anions) to the anode. Electrolyte is aqueous solutions of salts, acids or rules. In addition to the bodies of the properties described above, there are the body, in which electrons, circulating around the kernel is closely related to the atom or molecules. The body is so electrically neutral. Due to the lack of cargo carriers by the electric current does not flow. We call them epistolatory or dielectric Epistolatory body may be solid, liquid or gas. For Dnepropetrovsk of solids include glass, hard rubber, Mike, china, etc. from the bodies of liquid: distilled water, oil transformer; from the bodies of gas: air and other gases
