Thank you so much, I was looking at GCSE Textbooks, but even those are a little too simple, and definition- filled, doesn't really explain it (where does electromagnetism come from?) I read somewhere that it is because the electrons move a little bit faster than the protons, and due to the fact that faster objects are smaller, it leads to different densities, and the magnetic/electromagnetic field is formed. But I will look at the above links, and hopefully that should clear it up for now... only really need to understand it, and not really memorise anything for now, since I have already covered most of GCSE syllabus. Anyways, thank you once more, really helps
