No, electromagnets themselves do not release photon energy. Electromagnets are devices that use electric current to generate a magnetic field. When an electric current flows through a wire wrapped around a magnetic core, it creates a magnetic field in the vicinity of the electromagnet.
The generation of a magnetic field by an electromagnet is a result of the interaction between moving charges (electrons) and their associated magnetic fields. It is a purely classical phenomenon described by classical electromagnetism.
However, it's important to note that electromagnetic radiation, including photons, can be produced as a byproduct of certain processes involving electromagnets. For example, if an electric current flowing through an electromagnet is suddenly switched off, the changing magnetic field can induce an electric field in the vicinity. This changing electric field can give rise to electromagnetic waves, including photons, which propagate away from the electromagnet as electromagnetic radiation.
Similarly, when an electric current is switched on or off in a wire, there can be transient electromagnetic effects that can result in the emission of electromagnetic radiation. These effects are associated with the changing electric and magnetic fields that occur during the transient period.
So while electromagnets themselves do not directly release photon energy, processes associated with the operation or switching of electromagnets can lead to the emission of electromagnetic radiation, including photons.
