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.

My parents have a wireless phone charger. Problem is that it basically doesn't work when they have a case on their phones. Is there a solution to this (other than removing their phone case)?

I find the health aspects of radiations through induction charging worrying in principle, I have no idea how the potency compare to WIFI/5G radiation though but I would'nt risk it without studying the topic, it is absolutely not reasonable to trust our broken civilization on health topics, especially hypothetical oxidative and mutagenic long term only observable accelerated ageing.

radiations through induction

They basically do not radiate*. It is a near-field system, not an efficient antenna. Being near-field only means that the field strength drops off powerfully with distance. Sitting at your desk with a wireless charger on it has virtually no H-fields from the charger getting into your body. And those aren't dangerous anyways. There's absolutely no concern here.

*I mean, not more than all other electronics. Every conductor is a weak antenna and the FCC limits farfield emissions of all electronics so they don't cause interference.
