    1. The problem statement, all variables and given/known data
    I am high school student and was wondering how does electromagnetic field become existing? I konw equations describing are equations of max, but i do not understand how does field exist? equations of max describe but not tell why? that is my questions.


    2. Relevant equations
    Nabla dot E equals rho over epsilon not
    Nabla dot B equals to zero
    Nabla Cross E equals to negative dee bee dee tee
    Nabla Cross B equals myu not times J



    3. The attempt at a solution
    There is no attempt at a solutions.

    To put it bluntly, we don't know why. All theories must take something to be axiomatic. Maxwell's equations describe how the electromagnetic field works, they don't explain why it exists in the first place.
