2. Induction lamp - Wikipedia

   en.wikipedia.org/wiki/Induction_lamp

   A round Induction fluorescent lamp. The induction lamp, electrodeless lamp, or electrodeless induction lamp is a gas-discharge lamp in which an electric or magnetic field transfers the power required to generate light from outside the lamp envelope to the gas inside.

3. Electromagnetic induction - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_induction

   Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction .

4. Mechanically powered flashlight - Wikipedia

   en.wikipedia.org/.../Mechanically_powered_flashlight

   The linear induction, Faraday flashlight, or "shake flashlight" is another type of mechanically powered flashlight. It has been sold in the US beginning with direct marketing campaigns in 2002. This design contains a linear electrical generator which charges a supercapacitor which functions similarly to a rechargeable battery when the ...

5. Resonant inductive coupling - Wikipedia

   en.wikipedia.org/wiki/Resonant_inductive_coupling

   Resonant inductive coupling or magnetic phase synchronous coupling [4] [5] is a phenomenon with inductive coupling in which the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates. [5]

6. Energy saving lamp - Wikipedia

   en.wikipedia.org/wiki/Energy_saving_lamp

   Energy saving lamps are sources of artificial light that employ advanced technology to reduce the amount of electricity used to generate light, relative to traditional filament-burning light bulbs. Examples of energy saving lamps include: Fluorescent lamps; i.e. regular and compact; LED lamp; a Light-emitting electrochemical cell; Magnetic ...

7. Flashlight - Wikipedia
