Vacuum permittivity and the magnetic permeability change

Keywords: vacuum permittivity, vacuum magnetic permeability, the speed of light, Maxwell observer movement of electromagnetic energy

Can be inferred from the Maxwell equations, the light waves are electromagnetic waves. According to Maxwell's equations, we have introduced [1]. So we have come to the conclusion of the constant speed of light in a vacuum. Later we understand this is the speed of light is an absolute constant, namely the principle of constant speed of light. Permeability and permittivity are generally the same, then the the vacuum permeability capacitance outspoken unchanged it? [5]

One, the size of the electromagnetic energy by the Poynting vector determination, i.e. S = E x H, where s is the Poynting vector, E is the electric field strength, H is the magnetic field strength. E, H, S are perpendicular to each other constitute a right-handed spiral relationship; i.e. perpendicular to the unit area of ​​the electromagnetic energy by the S represents a unit time flowing through the unit is W / m².

Second, in 1905, the development of young Einstein Planck quantum. He believes that electromagnetic radiation is a essentially a non-continuous, both in atomic emission and absorption of their time, or in the dissemination process this. The energy of the product of the Planck's constant and the frequency of electromagnetic radiation, E = hv. [3]

One S = e × H is a unit time flowing through the unit area of ​​the electromagnetic energy in the vertical plane; II represented by E = hv is the energy of an electromagnetic wave, or that the total energy of the electromagnetic waves of a certain time. II E = hv S = E × H? If S = E = hv, What does it mean? Wherein E and H denote the average period of the electromagnetic wave electric field strength and magnetic field strength. When S = E, was the E × H = hv = 1 /  E  B. Thus, we concluded that if the frequency of the electromagnetic wave changes, then the average electric field strength of the electromagnetic wave and the average magnetic induction changes. Electromagnetic frequency becomes large, then the average electric field strength and the average magnetic induction of the electromagnetic wave strength becomes larger; Conversely, the electromagnetic wave frequency is smaller, then the average electric field strength and the average magnetic induction of the electromagnetic wave strength becomes small.

If the light source movement or observer movement, then the light have any effect? The movement can make the receiving frequency of the observer change. Based on the obtained, the light source or the movement of the observer can make the average electric field strength of the electromagnetic wave and the average magnetic induction intensity change. I.e., so that the electric field intensity of the light changes, so that the magnetic induction intensity of the light changes.

Then the light source or the movement of the observer so that the electric field intensity of the light to change, according to D = εE derived E = D / ε. The light source constant, can be considered as the D unchanged, therefore conclude that: the electric field intensity change is permittivity changes.

The capacitance ratio is unchanged, so the light source or the movement of the observer is equivalent to the medium or vacuum permittivity change.

Similarly, the magnetic induction intensity of the light source or the motion of the observer so that the light changes, according to B =  H, the light source remains unchanged, that H unchanged, therefore conclude that: the change in intensity of the magnetic induction is because the magnetic permeability occurred changes. The magnetic permeability is generally constant, and so the light source or the movement of the observer is equivalent to the medium or vacuum magnetic permeability changes.

So come to the conclusion, the light source or the movement of the observer, the equivalent change in the medium or vacuum permeability and permittivity.

That is according to the movement of the light source or the observer, then the observer, according to obtained the speed of light changes. In vacuo, and if the observer and the light source relative motion occurs, the speed of light will change.

Usually we come to the conclusion that the constant speed of light in a vacuum is the static conditions of the light source and the observer.

Also, in a different medium speed of light may be different, according to the formula E = hv too, the energy of the light does not change; according to B =  H, D = εE obtained, E and B are changed, according to S = 1 /  E  B, draw energy changes. So different medium corresponding to different values ​​of h. related to the capacitance ratio of the value of h and the medium and the magnetic permeability of the medium. In the previous article, we guess the value of h may be related to the charge of electricity [4], the value of h permittivity, permeability may be related to the electronic power.
