How does induction lamps work?

Magnetic induction lamps are basically fluorescent lamps with electromagnets wrapped around a part of the tube,or inserted inside the lamp.In external inductor lamps,high frequency energy from the electronic ballast, is sent through wires, which are wrapped in a coil around the ferrite inductor, creating a powerful magnet ,which travels through the glass and excites the mercury atoms in the interior which are provided by a pellet of amalgam (a solid form of mercury). The mercury atoms emit UV light . the UV light is up-converted to visible light by the phosphor coating on the inside of the tube.
