   en.wikipedia.org/wiki/Induction_cooking

   The global induction cooktops market was estimated at $9.16 billion in value during 2015. [citation needed] In April 2010, The New York Times reported that "In an independent survey [in 2009] by the market research company Mintel of 2,000 Internet users who own appliances, only 5 percent of respondents said they had an induction range or ...

4. Induction coil - Wikipedia

   en.wikipedia.org/wiki/Induction_coil

   For this reason, induction coils were called spark coils. An induction coil is traditionally characterised by the length of spark it can produce; a '4 inch' (10 cm) induction coil could produce a 4 inch spark. Until the development of the cathode ray oscilloscope, this was the most reliable measurement of peak voltage of such asymmetric ...

   He invented the first induction coil in 1836. [3] [4] [5] An induction coil produces an intermittent high-voltage alternating current from a low-voltage direct current supply. It has a primary coil consisting of a few turns of thick wire wound around an iron core and subjected to a low voltage (usually from a battery). Wound on top of this is a ...

7. Induction heating - Wikipedia

   en.wikipedia.org/wiki/Induction_heating

   Component of Stirling radioisotope generator is heated by induction during testing. Induction heating is the process of heating electrically conductive materials, namely metals or semi-conductors, by electromagnetic induction, through heat transfer passing through an inductor that creates an electromagnetic field within the coil to heat up and possibly melt steel, copper, brass, graphite, gold ...
