Abstract :
An investigation is carried out to assess the magnetic field levels produced by the currents flowing in two magnetically coupled coils in air used for wireless power transfer (WPT). The currents are determined by an equivalent circuit, while the magnetic field in the surrounding environment is numerically and analytically calculated. The simulation procedure is validated by comparison with experiments.
