Although he stated this in theory, how was he able to prove it possible. What measuring device do people use to prove that this theory is correct?

In summary, Gauss equations state that the flux of a gaussian surface is equal to the sum of all the electric field times the surface area. This is a purely mathematical result derived from Coulomb's Law. Gauss did not make any measurements to arrive at it, as Coulomb's law was known long before Gauss's law. However, to come up with the permittivity constant and other constants, it is likely that some measuring device was used to measure the charge of an object and its flux.

I am pretty sure they had to have had used something to measure the charge of an object and its flux to come up with the permittivity constant and etc.

Gauss used various instruments to measure flux and electric fields, including the electrometer, which measures the strength of electric fields, and the galvanometer, which measures the flow of electric current. He also used a device called the torsion balance, which uses a suspended wire to measure the strength of electric fields.

To prove his theory, Gauss conducted experiments using these instruments to measure the flux and electric fields on different surfaces and compared the results to his equations. He also used mathematical calculations and equations to further support his theory.

In modern times, scientists use advanced instruments such as the fluxmeter, which directly measures the electric flux, and the voltmeter, which measures the potential difference between two points and can be used to calculate the electric field. These instruments, along with computer simulations and mathematical modeling, allow us to further validate Gauss's theory and its applications in various fields of science and technology.

Flux is a measure of the flow of a physical quantity through a surface. In the context of electric fields, it refers to the amount of electric field lines passing through a given area.

Gauss used a device called a Gaussmeter, which is essentially a magnetometer, to measure the strength and direction of magnetic fields. He also used a special type of compass called a dip circle to measure the inclination of the Earth's magnetic field.

In addition to the Gaussmeter and dip circle, Gauss also used an electrometer to measure the strength of electric fields. This device measures the potential difference between two points in an electric field.

No, Gauss did not invent these instruments. The Gaussmeter and dip circle were already in use by other scientists, and the electrometer was invented by William Snow Harris in 1825.

Yes, modern versions of these instruments are still used today for measuring magnetic and electric fields. However, they have been greatly improved and updated with new technology.
