An oscillating magnetic field emits copious amounts of photons. An electron beam traveling through a spatially modulated magnetic field called a wiggler can be made to lase. It's called a free electron laser.

Not that i know of. But a changing magnetic field will create an electric field. The combinations of changing magnetic and electric fields propagates and carries energy. Turns out that there is a particle and wave duality in nature where the wave i described above can be shown to have particle like properties. The particle is know as the photon

In other way , the question implies, " whether a magnetic field can emit light or electro magnetic radiation?"

Unless there is an interaction between a magnetic field and an electric field , no e.m. radiation { photon} will be created. The interaction occurs, if a charge is rapidly accelrated.
Or if the magnetic field varies rapidly in the presence of a charge , e.m.radiation will be created.

no a photon is a release of energy. the magnetic field can cause a photon to be released but not from the field itself.

A white dwarf is a very powerful magnetic field (gravity folding matter) this compression forces the remaining matter in the star to emit photonic energy as well as wave type energies till exhausted. then the fiels collapses it to oblivion the ultra dense matter we know as a black dwarf . then if conditions are right a black hole

interesting..
did you mean lase? like a laser?
i dont think what you asked could happen. lasing involves a photon interacting with an electron, stimulating emission of a similar photon. which is part of where the name 'laser' comes from

* Of course the particles won't actually be in a particular state
until interactions with other particle, the environment in general,
force them to be in some particular state which with some non zero
probability is an excited state.
