What is Wireless Charging?
Wireless charging, also known as inductive charging, is a technology that enables you to recharge your phone’s battery without physically plugging it into a power source. It uses electromagnetic fields to transfer energy between a transmitter (the charging base) and a receiver (your phone) to refill your battery.
How Does Wireless Charging Work?
Wireless charging works on the principle of electromagnetic induction, which is similar to how a transformer works. Here’s a simplified explanation:
- The charging base contains a coil of wire (the transmitter) that carries an alternating current (AC).
- When you place your phone on the charging base, the receiver coil in your phone aligns with the transmitter coil.
- The AC in the transmitter coil induces an electromotive force (EMF) in the receiver coil.
- The EMF generates an alternating current in the receiver coil, which is then converted into direct current (DC) to charge your phone’s battery.

What is Wireless Charging?
Wireless charging, also known as inductive charging, is a technology that allows you to charge your device without physically plugging it into a power outlet. It works by transferring energy between a transmitter and a receiver through an electromagnetic field. This means that you can simply place your device on a wireless charging pad, and it will start charging without the need for cables or adapters.
The technology is based on the principle of electromagnetic induction, where an electrical current is created in a coil of wire when it is placed in a changing magnetic field. In wireless charging, the transmitter contains a coil that generates an electromagnetic field when an alternating current passes through it. The receiver, built into the device to be charged, has a coil that detects this field and converts it back into an electrical current, which is then used to charge the device’s battery.
How Does Wireless Charging Work?
Wireless charging works by creating an electromagnetic field between the transmitter and the receiver. When a device is placed on a wireless charging pad, the transmitter detects the presence of the receiver and begins to transmit energy through the electromagnetic field.
