The X-ray images reveal the internal structures of both devices.
Wireless charging operates without physical connections, utilizing electromagnetic induction through coils. When current flows through the transmission coil in the charger, it generates a magnetic field. Placing a smartphone within this field induces current in the phone's receiving coil, converting magnetic energy into electrical power for charging.
The smartphone image clearly shows various components including the lens, antenna, display, circuit board, and connectors, with detailed visibility of circuit board holes and electronic components, including ICs.
