Typically magnets are used to create a magnetic field in things, usually using permanent magnets or electrons.
Yes light is electromagnetic but electromagnetism is also part of the electroweak force.
Whether something is electronic, photonic or harnesses the weak force depends on where the majority of the interaction is. Photons don’t interact with the magnetic force but electrons which do generate photons when they change energy state.
You can use a photon to excite an electron which would have electromagnetic effects but it’s not typically what you’d use to induce magentism.
Eg. If I asked you to magnetize something you’d use a magnet or electromagnet and not a flash light.
