Thank you for the feedback. I'll review my notes and see if I can clarify this section - my key point there was simply to show that the magnetic field isn't really necessary - I wanted to show that it's all part of relativistic contractions made by the electric field. If I made any errors I give you my sincere apologies. Btw if you want to make edits to my work directly - you can find it as it's fully open source: https://github.com/photonlines/Intuitive-Guide-to-Maxwells-E...
