7:25 A coil can be used as an antenna and emit EM radiation and according to duality, photons. In the case of coupling of two coils we can transmit energy between the two coils with an efficiency higher than if the coils were not coupled or having the same shape size and number of turns. Does that mean the receiving coupled coil attracts photons?

The example can be continued with tuned receiving antennas at great distances from the emitting antennas. Some could say when resonating, a distant antenna may create its own EM fields and somehow capture more photons but photons cannot be diverted by EM fields. So the receiving antenna does get more EM energy by diverting the EM fields, but not the photons and the dualism principle is broken.

That's one of the reasons i believe in the case of low frequencies EM fields generated by antennas photons are not being emitted.
