ELI5: How do wireless phone charges work?

How does it manage to charge your phone through a entire rubber / plastic / metal case, and through the actual phone itself, and somehow penetrate the battery to charge it?

Any sort of electric current will generate a corresponding, changing magnetic field. Vice versa, a changing magnetic field will create a current in a nearby electrical circuit. This is how most electricity is generated; you physically move a magnet near a coil of wire to create a current, which is the electrical power that everyone uses.

So wireless charging uses the electrical current in the charger to create a changing magnetic field. This changing magnetic field, near a phone, will create an electrical current in the wireless charging "module" in the phone. The phone is designed to use that current to charge itself.
