In this blog post, we’ll delve into the science behind wireless charging, demystifying the process step-by-step. We’ll explore the role of coils, magnetic fields, and the charging process itself, leaving you with a clear and concise understanding of how your Samsung wireless charger brings power to your device.
The Science Behind Wireless Charging
Electromagnetic Induction: The Core Principle
At its heart, wireless charging relies on a phenomenon known as electromagnetic induction. This principle, discovered by Michael Faraday in the 19th century, states that a changing magnetic field can induce an electric current in a nearby conductor. Samsung wireless chargers leverage this principle to transfer energy from the charging pad to your compatible device.
How It Works: A Step-by-Step Explanation
1. The Transmitter Coil: Inside the wireless charging pad is a coil of wire called the transmitter coil. When you plug the charger into a power source, an alternating current (AC) flows through this coil.
2. Creating a Magnetic Field: This alternating current creates a fluctuating magnetic field around the transmitter coil.
3. The Receiver Coil: Your Samsung device, equipped with a receiver coil, is placed on the charging pad. This coil is positioned close to the transmitter coil.
4. Induction of Current: The fluctuating magnetic field from the transmitter coil induces an electric current in the receiver coil of your device.
5. Energy Conversion: The induced current in the receiver coil is then converted into direct current (DC) by a rectifier circuit within your device. This DC power is used to charge your battery.
Benefits of Wireless Charging
- Convenience: Simply place your device on the charging pad; no need for cables.
- Durability: Reduced wear and tear on charging ports by eliminating the need for repeated plugging and unplugging.

How Does a Samsung Wireless Charger Work?
The Basics of Wireless Charging
Wireless charging technology, also known as inductive charging, has been around for decades. It’s a process where an electromagnetic field is used to transfer energy between two coils. In the case of a Samsung wireless charger, the process is slightly more complex. The charger uses a technology called Qi (pronounced “chee”), which stands for “inductive charging” in Chinese.
The Qi standard is an open standard for wireless power transfer, developed by the Wireless Power Consortium. It allows devices from different manufacturers to charge wirelessly using a single charger. Samsung, as well as other leading manufacturers, has adopted the Qi standard for their wireless charging products.
When a Samsung phone or other Qi-enabled device is placed on a wireless charger, it creates a magnetic field between the charger and the device. This magnetic field induces an electrical current in the device’s receiver coil, which is then used to charge the device’s battery.
The Components of a Samsung Wireless Charger
A Samsung wireless charger consists of several key components:
- Transformer: This is the core component of a wireless charger. It’s responsible for transferring energy from the charger to the device.
- Coil: The coil is the receiver that picks up the electromagnetic field generated by the charger.
- Controller: The controller regulates the flow of energy from the charger to the device. It ensures that the energy is transferred safely and efficiently.
- Inductor: The inductor is a coil of wire that stores energy in a magnetic field.
How the Charger Transfers Energy
The process of transferring energy from the charger to the device is as follows:
1. The charger sends a high-frequency alternating current (AC) to the transformer.
2. The transformer converts the AC to a high-frequency electromagnetic field.
3. The electromagnetic field induces an electrical current in the device’s receiver coil.
4. The controller regulates the flow of energy from the charger to the device, ensuring that the energy is transferred safely and efficiently.

The Power of Induction: Understanding the Technology Behind Wireless Charging
At the heart of every Samsung wireless charger lies the fascinating principle of electromagnetic induction. This technology, discovered by Michael Faraday in the 19th century, forms the basis for wireless power transfer. Essentially, it involves creating a fluctuating magnetic field that induces an electrical current in a nearby conductor.
How Does Induction Work?
Imagine a coil of wire (the transmitter coil) connected to an AC power source. When the electricity flows through this coil, it generates a fluctuating magnetic field around it. Now, place a second coil (the receiver coil) within this magnetic field. The changing magnetic field interacts with the receiver coil, inducing an electrical current within it. This induced current can then be used to charge a compatible device.
The Role of Resonant Frequencies
While the basic principle of induction is straightforward, modern wireless chargers like those from Samsung employ a technique called resonant inductive coupling to enhance efficiency and range. This involves both the transmitter and receiver coils operating at the same resonant frequency. Think of it like tuning a radio; when both the transmitter and receiver are tuned to the same frequency, the signal is received more strongly.
Resonant inductive coupling allows for more efficient power transfer over a slightly greater distance compared to traditional inductive charging. This is why you can place your Samsung device on the charger without needing to align it perfectly.
Safety and Efficiency
Samsung wireless chargers are designed with multiple safety features to ensure safe and efficient charging. These include:
- Overheating Protection: The charger monitors its temperature and automatically reduces power output if it gets too hot.
- Foreign Object Detection: Sensors detect if a non-compatible object is placed on the charger, preventing potential damage.
- Short-Circuit Protection: The charger shuts down if a short circuit is detected, protecting both the device and the charger.
