Without the need of physical connectors or cables, wireless power transfer transfers electrical energy from a power source to an electrical device via electromagnetic fields. While there are other techniques for wireless power transfer, inductive coupling is one of the most widely used strategies. This is a condensed description of how it functions:
Transmitter Coil: A base station or charging pad is part of a wireless charging setup. There is a wire coil in this pad. This coil creates an electromagnetic field around it as electricity passes through it. Consider it as an energy ring of magic.
Receiver Coil: Another wire coil is located inside the gadget you wish to charge, such a smart phone. We refer to this as the receiving coil. It's refer to this as the receiving coil. Its purpose is to absorb energy from the electromagnetic field that the transmitter coil generates.
Alignment: The transmitter and receiver coils must be in close proximity to one another and correctly aligned in order for wireless charging to function effectively. For this reason, the charging station must be appropriately positioned for your device.
Transfer of Energy: The electromagnetic field produced by the transmitter coil causes a current to flow through the reception coil when the coils are near together and aligned. The gadget can be powered directly by this current or used to charge its battery.
Charging: The gadget is charged via electrical current that enters its battery in the same way as if a cable were being plugged into a charger.
In order to transport electrical energy wireless that is without the need of physical wires from the charging pad (transmitter) to the device (receiver), electromagnetic fields are used. With this technology, gadgets start charging wireless as soon as you place them on the charging pad; there is no need to plug them in and unhook them.
