This desk lamp utilizes mutual induction*, the wireless flow of electric current. Coils and magnets are included in the main body and in a separate floating sphere. When this spherical planet is moved to specific positions, such as getting into orbit, the lamp turns on and the amount of light is adjusted.
The internal magnets and coils give a new operational feeling. A new way of brightness control is also developed. The more the coils are wound, the more electric current they receive. This system can adjust quantity of light without complicated electric circuits.

*mutual induction
The production of an electromotive force in a circuit by a change in the current in an adjacent circuit which is linked to the first by the flux lines of a magnetic field. -Oxford Dictionary
