Wireless Charging Isn't What You Think (It's Not the Magnets)

Your phone is charging… but nothing is plugged in. No cable. No metal contacts. So how does electricity get into the battery? In this video we open up a wireless charger and follow the energy step by step: the copper coils hidden inside, how electromagnetic induction works, why the current has to keep changing, why your phone has to sit almost perfectly on the pad, what the magnets are really for (spoiler: they don't charge anything), why wireless charging makes your phone warm, and how the charger knows not to heat up a stray coin. ⏱️ Chapters 0:00 Charging with no cable? 0:22 What actually charges your phone? 0:43 How does electricity cross the gap?
