It would seem to be magical. Here's this thing that allows you to move huge amounts of power over vast distances, but deposit it in whatever tiny portions you like, in whatever room you want, and it's so easy you run the wires along your existing walls.
The same force allows you to send both signal and power through thin air. And if you don't want it there, you can shield from it.
Or you can make a motor quite elegantly by winding some wires.
And you can manipulate it so finely that you can do calculations with teeny tiny amounts of it. And store the results.
But one thing I was wondering was how much it depends on basic science. Now that we've discovered EM, have we exhausted the basic knowledge about the world? Is every tech going forward just refinements on particular aspects of nature, or is it unlimited how we combine things?
