how does wireless electricity transmission work?
In: 4
The same way a microwave heats food, but different enough to not cook you.
A microwave sends high energy radio waves inside a box, which transfers the energy into food.
Wireless charging sends high-energy electromagnetic waves into a phone, which then turns that energy into charge.
The only difference is a microwave sends a ton of energy randomly. A charger sends a lot less energy in specific coils, and only works if there are specific “receiver” coils on the other end. If not, or if the distance is too far, it doesn’t pick it up and no charging happens.
