Technology Review: TR10: Wireless Power“The researchers built two resonant copper coils and hung them from the ceiling, about two meters apart. When they plugged one coil into the wall, alternating current flowed through it, creating a magnetic field. The second coil, tuned to the same frequency and hooked to a light bulb, reso­nated with the magnetic field, generating an electric current that lit up the bulb—even with a thin wall between the coils.”
