This innovative technology has been gaining popularity in recent years, and the iPhone 8 is one of the many devices that support wireless charging. But have you ever wondered how wireless charging works?
Inductive Charging Principle
The principle behind wireless charging is based on electromagnetic induction, which is a fundamental concept in physics. Electromagnetic induction is the process of generating an electric current in a conductor when it is placed in a changing magnetic field. This phenomenon was first discovered by Michael Faraday in 1831 and is the basis for many modern technologies, including generators, motors, and transformers.
In the context of wireless charging, a coil of wire, known as the transmitter coil, is placed in the charging base or pad. When an alternating current (AC) flows through the transmitter coil, it generates a magnetic field around it. This magnetic field induces an electromotive force (EMF) in a nearby coil of wire, known as the receiver coil, which is embedded in the device to be charged, such as the iPhone 8.
Wireless Charging Standards
There are several wireless charging standards, including Qi (pronounced “chee”), AirFuel, and Rezence. Qi is the most widely adopted standard and is supported by the iPhone 8. Qi is an open standard, which means that any manufacturer can use it in their products, making it a widely compatible technology.
Qi wireless charging uses a frequency of 100-200 kHz and operates at a power level of up to 15 watts. This means that Qi-enabled devices, such as the iPhone 8, can charge at a rate of up to 15 watts, which is comparable to traditional wired charging.
How Wireless Charging Works in iPhone 8
