You might be thinking &amp;quot;but magnetic fields are intimately tied to cross products, which only work in three dimensions.&amp;quot; But you can set up the equations of electromagnetism just fine either using differential forms or bivector magnetism (https://arxiv.org/abs/2309.02548), and it works in any dimension you&amp;#x27;d like. (The cross product version is really a narrow and sometimes misleading special case.)
