FIELD: electricity.
SUBSTANCE: invention includes power accumulating device (150) identified as object for power supply, and secondary self-resonating coil (110) receiving electric power that should be supplied to the said load from external primary self-resonating coil (240). The secondary self-resonating coil (110) is capable of switching between the first condition and second condition. The first condition is selected in power receiving mode, in which the secondary self-resonating coil has magnetic link with primary self-resonating coil (240) by way of magnetic field resonance. The second condition is selected in power receiving stop mode, in which magnetic link of the secondary self-resonating coil with primary self-resonating coil by way of resonance is weaker than in the first condition.
EFFECT: possibility to stop power receiving.
