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 ...
If an induction cooktop is 84% efficient and a smooth top is 74% efficient, how much less energy does the induction top use? 12%, not 10%. To put 100 units of heat in the pot, an induction top will consume 100/.84 = 119 units of energy from the line. A smooth top will take 100/.74 = 135. (135-119)/135 = 12%.
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 ...

A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run capacitor). [2]
The motor has a stator and a rotor but there is no electrical connection between the two and the rotor current is generated by induction.The rotor winding is connected to a commutator which is in contact with a short-circuited pair of brushes which can be moved to change their angular position relative to an imaginary line drawn through the axis of the stator.
