A method for inductive energy transmission between a primary part and a secondary part, wherein a primary current is introduced into a transmitting coil arranged on the primary part in order to create a first magnetic field which induces an electrical AC voltage in a receiving coil arranged on the secondary part, which electrical AC voltage causes an electrical secondary current at the secondary part and thus a power flow to at least one load connected to the receiving coil, which power flow comprises an uncompensated active power, it is provided that a compensation unit introduces a compensation current into a secondary-side coil, which compensation current generates a second magnetic field which is superimposed on the first magnetic field and induces a compensation voltage in the transmitting coil. The compensation voltage changes the phase shift between the primary voltage that drops across the transmitting coil and the primary current flowing through the transmitting coil in such a way that the transmitted active power is increased.
