About the working principle of mobile phone wireless charging
The working principle of the wireless charger is to use the "resonance" principle of physics-two objects with the same vibration frequency that can efficiently transmit energy.
1. The electric energy in the transmission line is transmitted into the antenna made of copper.
2. The antenna vibrates at a frequency of 10 MHz, generating electromagnetic waves.
3. The energy emitted by the antenna travels 2 meters (6.5 feet) away.
4. The laptop computer that also vibrates at a frequency of 10 MHz receives current and energy is charged into the device.
5. The energy that is not converted into the laptop will not be re-absorbed by the antenna. People and other objects that cannot produce 10 MHz resonance will not interfere with it
