wait till you learn how the electric force and the magnetic force interact with each other such that an electric force causes a magnetic force in front of it, and then that new magnetic force then causes a new electric force in front of it, and like so they recursively sustain each other, such that they self-propagate over vast distances (unlike just a magnetic field which fades off as you get further away), and what do we call such an infinitely self-propagating electromagnetic wave? a photon

I've taken a few physics classes that covered such topics. Just today I was winding some copper wire into a coil and then winding another wire into coils around every couple of loops of the original wire. I don't know enough physics to predict what kind of magnet field running a current through the two coils would produce. Probably create a black hole or something /s. Seriously though, are there tools to stimulate magnetic induction fields in coils of wire?

  That copper coil should do it on its own in some capacity. Drop a magnet or something through the coil. It should slow down passing through. Lenz's Law.

  Not only are there tools for it, it's such a common problem that there's a Wikipedia list of just the solvers that are notable enough to have dedicated articles: https://en.wikipedia.org/wiki/Comparison_of_EM_simulation_software https://en.wikipedia.org/wiki/Comparison_of_EM_simulation_so... Be warned that the learning curve tends to be steep if you don't have the background down. It's far simpler in most cases to approximate your circuits and say "Good enough" unless you're venturing into pretty wild territory (antennas and high frequency), so most of the offerings tend to be either academic, military, or high end commercially focused.

I have often wondered if something like that is the physical basis of momentum, or at least contributes to it such that apparent mass is incorrect for charged particles.
