Physics behind
Wireless charging, also known as inductive charging, is a revolutionary technology that enables the transfer of electrical energy between a charging pad or base station and a device without the need for physical connectors or cables. This remarkable process relies on the principle of electromagnetic induction.
At the core of wireless charging is a simple yet effective mechanism. The charging pad contains a coil of wire that’s connected to an electrical current source. When electricity flows through this coil, it generates an electromagnetic field around it. This field extends from the charging pad and envelops the device in need of charging.
The device, such as a smartphone, must also be equipped with a coil, typically situated on its back or within its casing. This coil is designed to resonate with the electromagnetic field generated by the charging pad. When the two coils are aligned correctly, the electromagnetic field induces an electrical current in the device’s coil. This current is then converted into direct current (DC) to charge the device’s battery. It’s essentially the same principle that allows transformers to transfer electricity from one coil to another.
