I know it's an ancient meme to ask "How do magnets work" but I genuinely do not understand it, and I especially don't understand how a magnetic field is different from an electric field. Apparently they're both caused by electrically charged particles and they behave in very similar ways (opposite charges attract each others, same charges repel each others) but they're still different. How? What's the fundamental difference between these two? And please, I'm begging for a simple explanation. Answer these questions for me in the simplest way possible, like you were explaining it to a school kid:
