How wireless charging works

How can energy be transferred through air from one part to the other? The way wireless charging works is by something which is called magnetic induction. Firstly discovered in the 1830’s by Michael Faraday, he discovered that when you move a permanent magnet in and out of a single loop of wire, it induces a voltage. Linking electricity with magnetism. Let’s explain by conducting an experiment:

take a permanent magnet – like the ones you stick on your fridge;

Connect a light bulb to a simple loop of copper wire;

Move the magnet quickly back and forth, bringing it closer and further away from the loop;

The bulb will start lighting up a little!

So what just happened? Why did the bulb light up? By bringing the magnet back and forth, you change the magnetic field experienced by the loop, which induces a voltage in the loop. The voltage created is in some way comparable to the voltage of a battery.
