I don't at all understand how wireless charging works.
It's actually quite simple.
In the wireless charger, you have a coil. When you run an alternating current through a coil, it generates an alternating magnetic field.
In the phone, you have another coil. When it is placed in close proximity to that alternating magnetic field, that field generates an electrical current in the coil.
That electrical current in the coil is then used by the phone to charge.
So on one end you're using electricity from the wall to generate a magnetic field, and then on the other end you're using that magnetic field to generate electricity. It's just transforming one type of energy into another, and then back again.
The interplay between electricity and magnetism is how electric motors work, how hydroelectric dams work, how gas generators work, etc. Strange and wonderful things can happen when electricity and magnetism interact
