What exactly is an EMP (Electromagnetic-pulse)? Isn’t light just an electromagnetic beam? How exactly is light and electromagnetism connected?

Question

Hello all,

I’m working on a sci-fi project rn, and one of the creatures communicates telepathically via electromagnetic waves. However, I’m kinda confused as to exactly what “electromagnetic” means. EMPs, electromagnets, and (from what I can tell) light are all electromagnetic, what do they have in common that makes them such?

Thanks in advance 🙂

EDIT: I know I said “how is these things connected in the title”, forgive my grammar mistakes ;-;

Think of a single photon of light as a single drop of water. Noce and concenient coming put of your hose or sink, right? An EMP is the tsunami version of that.
