Explaining the electric fields of particles

Click For Summary
SUMMARY

The discussion centers on the relationship between electric fields and changing magnetic fields, particularly in the context of subatomic particles. It is established that electric fields are inherent properties of charged particles, and while changing magnetic fields can generate electric fields, they are not the sole source. The conversation highlights a shift from field-based explanations to particle physics, emphasizing that photons serve as the force carriers for electromagnetic fields. This transition reflects current trends in quantum physics understanding.

I haven't taken any course in quantum field theory or read any advanced books about it, but I would like to make what I think is a deduction.

An electric field can be explained by changing magnetic field. Provided that some property of this changing magnetic field was met, the electric field may correspond to the electric field produced by a subatomic particle. So far, I don't know of any other type of field that would generate an electric field other than a changing magnetic field. Do the quantum physicists explain the electric field of subatomic particles this way? Do they know the changing magnetic field that would be necesary to generate the electric potential of the proton for instance?

You don't need a changing magnetic field to make an electric field, electric fields are inherent properties of charged particles. If you're saying the only 'field' that can generate an electric field is a changing magnetic one you are correct, however using this sort of field thinking is, as far as i know, being phased out in this line of thought and replaced with particle physics, whereby the force carriers of the EM fields are photons.
