Abstract: A contact-free inductive power transfer system for minimizing the radiating magnetic field in the vicinity of the transmission zone. The system includes a primary coil (9) of n1 turns and a secondary coil (10) of n2 turns. In operation, the same volume of current is circulated in the primary and in the secondary coil during transfer and the number of turns n1 in the primary coil multiplied by the current circulating in the primary coil is equal to the number of turns n2 in the secondary coil multiplied by the current circulating in the secondary coil, the currents circulating in the primary and secondary coil being in phase opposition so as to minimize the radiating magnetic field generated by the coils. An installation for energizing a movable vehicle (14) through an intermediate loading station (6) is also described.
