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 ;-;

Well, electromagnets are magnets we’ve made by using electricity. By winding up cables into coils, you’ll get a magnet which you can turn off and om; change the polarity. Which is a popular thing to do in science fiction. ‘normal’ electrity in a single cable forms a magnetic field around it (thus electromagnetic). By winding and stacking cables you amplify that effect. This field consists of waves; radiation. Like microwave, or x-ray, radio, wifi. Light also behaves in this way (sometimes, otherwise I’ll get some physicists mad) an emp is basically an bomb of the these waves, to overload everything in its path. Computers run on electricity, and magnetic field can be disturbed if something is strong enough. Or an emp is small and could be used for something like communication. It’s a pulse, a directed signal with specific characteristics. Could indeed be used for communication. But I think that in popculture it’s mostly a weapon to disarm everything electrical.
