Curiosities in electricity, magnetics and electrodynamics

1. The problem statement, all variables and given/known data
I'm about to write a paper on electrodynamics. It's supposed to be a summary of the entire course, but we're allowed to go on tangent and write about more exciting things than Gauss' law for example. This can really be anything that we'd like. Do you have any ideas?


2. Relevant equations



3. The attempt at a solution
I currently don't have any ideas as to what this could be.
