  2. Induction heating - Wikipedia

    en.wikipedia.org/wiki/Induction_heating

    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, silver, aluminum, or carbide.

  3. Induction heater - Wikipedia

    en.wikipedia.org/wiki/Induction_heater

    Induction heating is a non contact method of heating a conductive body by utilising a strong magnetic field.Supply (mains) frequency 50 Hz or 60 Hz induction heaters incorporate a coil directly fed from the electricity supply, typically for lower power industrial applications where lower surface temperatures are required.

  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 ...

  5. Induction furnace - Wikipedia

    en.wikipedia.org/wiki/Induction_furnace

    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 .

  6. Induction hardening - Wikipedia

    en.wikipedia.org/wiki/Induction_hardening

    Induction heating is a non contact heating process which uses the principle of electromagnetic induction to produce heat inside the surface layer of a work-piece. By placing a conductive material into a strong alternating magnetic field, electric current can be made to flow in the material thereby creating heat due to the I 2 R losses in the material.

  7. Induction shrink fitting - Wikipedia

    en.wikipedia.org/wiki/Induction_shrink_fitting

    Induction heating is a non contact heating process which uses the principle of electromagnetism induction to produce heat in a work-piece. In this case thermal expansion is used in a mechanical application to fit parts over one another, e.g. a bushing can be fitted over a shaft by making its inner diameter slightly smaller than the diameter of the shaft, then heating it until it fits over the ...

  8. Flux linkage - Wikipedia

    en.wikipedia.org/wiki/Flux_linkage

    Thus, for a typical inductance (a coil of conducting wire), the flux linkage is equivalent to magnetic flux, which is the total magnetic field passing through the surface (i.e., normal to that surface) formed by a closed conducting loop coil and is determined by the number of turns in the coil and the magnetic field, i.e.,

  9. Electromagnetic coil - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_coil

    A coil with a core which is a straight bar or other non-loop shape is called an open-core coil. This has lower magnetic field and inductance than a closed core, but is often used to prevent magnetic saturation of the core. A coil without a ferromagnetic core is called an air-core coil. [14]
