Did You Know? Your Wireless Charger Contains a Coil Tool ?

Many people think of wireless charging as simply a convenient way to charge a smartphone without plugging in a cable. But did you know that the key component behind this technology is the coil—the very same principle used in industrial induction heating systems?

Inside every wireless charging pad is a transmitter coil made of copper. When alternating current (AC) flows through the coil, it generates an alternating magnetic field. When a compatible smartphone is placed on the charging pad, a receiver coil inside the phone captures this magnetic field and converts it back into electrical energy to charge the battery.

Although Wireless Charging and Induction Heating serve different purposes, they are both based on the same fundamental principle: Electromagnetic Induction.
