Yo I kind of felt bad for Angel Knight in this thread. I was laughing the whole time when you commented though.
I was actually able to find it through google.
@Xdqwerty, power through a coil of wire causes an electromagnetic field to be generated. Another coil of wire can be set up to harness the power from that electromagnetic field and turn it into usable energy for charging a device
@Xdqwerty, wire is definitely more practical IMO. Hell these days you can charge a laptop over USB, can't charge a laptop wirelessly though. Wireless chargers, even "fast" ones, are only good for slowly charging devices, plus they generate a good amount of heat too
