How Magnetic Wireless Charging Works
Magnetic wireless charging uses the principle of electromagnetic induction to transfer energy between a transmitter (the charging base) and a receiver (the device to be charged). The transmitter contains a coil of wire, known as the transmitter coil, which carries an alternating current (AC). When a device with a receiver coil is placed on the transmitter, an electromagnetic field is generated, inducing a voltage in the receiver coil. This voltage is then used to charge the device’s battery.
The Science Behind Electromagnetic Induction
Electromagnetic induction is a fundamental principle of physics that was discovered by Michael Faraday in 1831. It states that an electric current is generated in a conductor when it is exposed to a changing magnetic field. In the case of magnetic wireless charging, the transmitter coil creates a changing magnetic field, which induces a voltage in the receiver coil.

What Is Magnetic Wireless Charging And How Does It Work?
Magnetic wireless charging is a technology that allows devices to be charged without the need for cables or direct contact with a charging surface. It works by using a magnetic field to transfer energy between a transmitter, typically a charging pad or base, and a receiver, typically a device such as a smartphone or watch. The transmitter contains a coil of wire that carries an alternating current, which generates a magnetic field. The receiver contains a similar coil that detects the magnetic field and converts it back into an electrical current, which is then used to charge the device.
The technology behind magnetic wireless charging is based on the principle of electromagnetic induction, which was discovered by Michael Faraday in 1831. This principle states that an electric current can be generated in a conductor by changing the magnetic field around it. In the case of magnetic wireless charging, the changing magnetic field is created by the transmitter coil, and the receiver coil detects this change and converts it into an electrical current. This technology has been widely adopted in various applications, including consumer electronics, medical devices, and electric vehicles.
