Primary Side (Ground Transmitter)
Secondary Side (Vehicle Receiver)
Wireless power operates on the principle of induction. Alternating current in one coil produces a magnetic field, which then induces a current in the second coil. Water and human tissue are nearly transparent to the magnetic field.
