Side view of an induction cooktop. An induction cooker wirelessly transfers electrical energy by induction from a coil of wire into a metal vessel. The coil is mounted under the cooking surface, and a low-radio-frequency (typically ~25–50 kHz [1]) alternating current is passed through it. The current in the coil creates a dynamic ...
A kitchen stove, cooker, or cookstove is a kitchen appliance designed for the purpose of cooking food. Kitchen stoves rely on the application of direct heat for the cooking process and may also contain an oven underneath or to the side that is used for baking. Traditionally these have been fueled by wood; the earliest known example of such was ...
The Neijing image of a mountain with crags on the skull and spinal column elaborates upon the "body-as-mountain" metaphor, first recorded in 1227 CE (Despeux and Kohn 2003:185). The head shows Kunlun Mountains , upper dantian "cinnabar field", Laozi , Bodhidharma , and two circles for the eyes (labelled "sun" and "moon").
A wood-burning iron stove A stove at Holzwarth Ranch, Colorado. A kitchen stove, often called simply a stove or a cooker, is a kitchen appliance designed for the purpose of cooking food. Kitchen stoves rely on the application of direct heat for the cooking process and may also contain an oven, used for baking. "Cookstoves" (also called "cooking ...
An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. [ 1 ] [ 2 ] [ 3 ] Induction furnace capacities range from less than one kilogram to one hundred tons, and are used to melt iron and steel , copper , aluminum , and precious metals .
Most induction heating devices (with induction frequency control) have a frequency range of 100 kHz to 200 kHz. The output range typically incorporates 2.5 kW to 40 kW. Induction heaters in this range are used for smaller components and applications such as induction hardening an engine valve. [5] MF induction generators work from 1 kHz to 10 ...

The circle diagram can be drawn for alternators, synchronous motors, transformers, induction motors. The Heyland diagram is an approximate representation of a circle diagram applied to induction motors, which assumes that stator input voltage, rotor resistance and rotor reactance are constant and stator resistance and core loss are zero.
