The earth's iron core is a natural collector of these waves, which is why lightning is attracted to the earth. The lightning is a separation of the light and its magnetism, and the light escapes into space/heats the atmosphere while the magnetism is drawn into the earth, adding its energy to the magnetic field. We can make our own electromagnetic waves using metallic wires because we mined the metals from the ground, which is where the magnetism is stored.
