This paper proposes wireless power transfer (WPT) system with Halbach coils to reduce leakage magnetic flux. The transmission coil using the Halbach coils generates magnetic flux in the vertical direction and coils that generate a magnetic flux in the horizontal direction. The WPT systems with Halbach and spiral coils are developed and experimentally tested to verify the effect of reducing the leakage magnetic flux density. The experimental results show that the magnetic flux density decreases by 35.6% at maximum.
