In this case, the electromagnetic field. As I understand field theory, it states that forces exist as fields everywhere through spacetime. Perturbations in that field, where it rises to a non zero value, are interpreted as force carrying particles or bosons. So we could state that the photon is an excitation in the electromagnetic field just as the W and Z bosons are for the weak field.

Light is a collection of photons. Photons are the carrier particle of electromagnetism.
Another way of thinking of carrier particles is thst they are excitations of a pre-existing field. So photons (light) are an excitation of the electromagnetic field.

This is why such a big deal was made of the discovery of the Higgs boson, as it provided evidence for the Higgs field.

To your other question, any moving magnet does perturb the electromagnetic field and creates electricity in an electrical conductor; this is essentially known as Faraday's law.
