Small-Scale Question Sunday for January 22, 2023

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

Physically, it works the same way a transformer works -- induction. When you plug your phone (or computer, etc) into the wall, there is a transformer in the circuit stepping down the voltage. There is no basis to be worried about risks from inductive chargers any more than you worry about risks from transformers. Also this isn't some "new untested science" this is Maxwell's Equations, stuff we've understood since the 1860s.
