Understanding Electromagnetic Flux and the Electric Field: A Simple Explanation

In summary, electromagnetic flux is the surface integral of a vector field. A vector field is a mathematical concept that represents a physical quantity, such as the electric field. The electric field can be explained using the gravitational potential as an example. To understand more about electromagnetism, it is recommended to read an introductory text or consult resources such as Wikipedia and HyperPhysics.

What exactly is electromagnetic flux?
In wikipedia I read it is the " surface integral of a vector field" what is a vector field?

Is it the electric field.

What exactly is the electric field? Please explain it to me with using gravitational peotential, etc. as an example.

How is the charge inside a charged sphere nil?

I think you should look up an introductory text on electromagnetism. We won't be typing up one for you here, you know :smile:
If you want, we can try to find some ressources, but the best thing is probably to read a book on it and if you have questions, to come here.

For starters, you can look here:

1. What is flux?

Flux is a measure of the flow of a physical quantity through a surface. It can be thought of as the amount of something passing through a given area in a given amount of time.

2. How is flux calculated?

Flux is calculated by taking the dot product of the vector field and the surface normal, and then integrating this value over the surface. This can also be represented mathematically as the surface integral of the dot product of the vector field and the differential element of the surface.

3. What is Gauss's theorem?

Gauss's theorem, also known as the divergence theorem, states that the surface integral of a vector field over a closed surface is equal to the volume integral of the divergence of that vector field over the enclosed volume.

4. How is Gauss's theorem used in physics?

Gauss's theorem is used in physics to relate the flux of a vector field through a closed surface to the behavior of that vector field within the enclosed volume. It allows for the calculation of a physical quantity within a volume based on measurements taken on the surface of that volume.

5. What are some real-world applications of Flux and Gauss's theorem?

Some real-world applications of Flux and Gauss's theorem include calculating the electric field within a charged sphere, analyzing the flow of fluids through a pipe, and understanding the distribution of heat within a solid object.
