Wireless charging uses an electromagnetic field to transfer energy between two objects through electromagnetic induction. This is usually done with a charging station. You may be familiar with wireless chargers used by popular mobile phones and other gadgets. If you notice, those chargers don’t always work with every device.

In order to work, both the devices i.e. the charger & the mobile device should be equipped with induction coils for charging. But it is not as simple as just fitting the device with inductor coils. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.
