“…The Halbach array consists of Permanent Magnets (PM) arranged in a way that strengthens the magnetic field on one side and weakens it on the other side [20][21][22]. PM Halbach array have been applied in various applications such as magnetic levitation (Maglev) [23], linear motors [24], and energy harvesting [25]. However, the static single-sided magnetic field generated by PM Halbach arrays is not suitable for AC applications.…”

A mathematical model is presented for the optimisation of an Electromagnetic Halbach Array (EHA) for wireless power transfer. The mathematical model is based on Biot‐Savart's law of magnetic field in a current‐carrying square loop. The model is validated through static electromagnetic simulations in ANSYS Maxwell and found to be accurate and effective when predicting the magnetic field within the EHA box. To verify the analytical and simulation results, an EHA was fabricated, and experimental verification was carried out. The results show that the mathematical model can be widely used in the analysis and design optimisation of EHAs of any size and with diverse parameters in the case of single‐layer square spiral planar coils.
