Maxwells equation in cgs system

In summary, Maxwell's equations are fundamental equations that describe the behavior of electric and magnetic fields in the cgs system, which is commonly used in electromagnetism. They are written in Gaussian units, which simplifies calculations and allows for easier interpretation of results. These equations can also be applied in other unit systems, but the values for the electric and magnetic constants will differ. They are closely related to other fundamental laws of physics and are essential for understanding electromagnetic phenomena.

hi, I have just encountered following Maxwell equation in cgs system ▽×H = (1/c)((∂D)/(∂t))+((4π)/c)j,
▽×E = -(1/c)((∂B)/(∂t)),
▽.D = 4πρ,
▽.B = 0,
now , c is the speed of light in vacuum ,
my question is that we have studied earlier equation without this factor 'c' and 4pi in third equation, so how we get above equation in cgs( centimeter, gram, second ) system.

Related to Maxwells equation in cgs system

1. What is the significance of Maxwell's equations in the cgs system?

The cgs system, or the centimeter-gram-second system, is a unit system commonly used in electromagnetism. Maxwell's equations, a set of four equations that describe the behavior of electric and magnetic fields, are particularly important in this system as they provide a fundamental understanding of the relationships between these fields.

2. How are Maxwell's equations written in the cgs system?

In the cgs system, Maxwell's equations are written in Gaussian units, where electric and magnetic fields are measured in units of statvolts/cm and statamperes/cm, respectively. The equations themselves remain the same as in other unit systems, but the values for the electric and magnetic constants are different.

3. What are the benefits of using the cgs system for Maxwell's equations?

The cgs system is particularly useful in the study of electromagnetism as it simplifies the equations and allows for easier calculation and interpretation of results. Additionally, many physical phenomena are more easily understood and described using cgs units.

4. Can Maxwell's equations be applied in other unit systems?

Yes, Maxwell's equations can be written and applied in various unit systems, including the cgs system, mks system, and SI system. However, the values for the electric and magnetic constants will differ in each system, which may affect the numerical values in the equations.

5. How do Maxwell's equations in the cgs system relate to other fundamental laws of physics?

Maxwell's equations are considered one of the most fundamental laws of physics, as they describe the behavior of electric and magnetic fields and their interactions with matter. They are closely related to other fundamental laws, such as Coulomb's law, Faraday's law, and Gauss's law, and are essential for understanding and predicting the behavior of electromagnetic phenomena.
