Electricity must be different degrees within the range contain magnetic content

According viewpoint of modern physics, the magnetic charge phenomenon is generated by the motion, and thus in the range of electrical necessarily contain varying degrees of magnetic content. Therefore, the content of the electromagnetic and electrical difficult distinct from, and "Electricity" is sometimes also as "electromagnetism" for short.
Electromagnetic  electric meter  lies not only in the theory dominates all macroscopic electromagnetic phenomena (including static, static magnetic field, electromagnetic induction, circuits, electromagnetic waves, etc.), but also because it is united in optical  Voltage stabilizer  the framework of this theory, and deeply affecting people understand the idea of ​​the material world.
Discovery of the electron, so that electromagnetism and the theory of atomic structure and material  power transformers electron theory of macroscopic electromagnetic properties of substances attributed to the effect of the electrons in atoms, unified explanation of electric, magnetic, optical phenomena.
