In college, before we covered this in class, but after basic relativity, they assigned a homework assignment that said “Show that magnetism is just a relativistic effect of the electric force.” Yay.

I did not quite solve it but I had a “fun” 4 hours trying and could see the basic effect. If school were always like that, I would have enjoyed school a lot more + come out of it having learned a lot more.
