  2. 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.

  3. 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 ...

  4. 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.

  5. Magnetic Thermodynamic Systems - Wikipedia

    en.wikipedia.org/wiki/Magnetic_Thermodynamic_Systems

    Assuming the external magnetic field is uniform and shares a common axis with the paramagnet, the extensive parameter characterizing the magnetic state is , the magnetic dipole moment of the system. The fundamental thermodynamic relation describing the system will then be of the form U = U ( S , V , I , N ) {\displaystyle U=U(S,V,I,N)} .

  6. Magnetic stirrer - Wikipedia

    en.wikipedia.org/wiki/Magnetic_stirrer

    In synthetic chemistry, a combined magnetic stirrer/heater, equipped with a built-in temperature control mechanism and temperature probe, is commonly used with a heating bath (commonly oil, sand, or low-melting metal) or cooling bath (commonly water, ice, or an organic liquid mixed with liquid nitrogen or dry ice as coolant), allowing reactions ...

    Space heaters are repeatedly linked with tragedies. Local fire departments responded to an estimated average of 44,210 home structure fires caused by heating equipment, including space heaters ...

  8. Thermo-magnetic motor - Wikipedia

    en.wikipedia.org/wiki/Thermo-magnetic_motor

    These systems operate in a magnetic Brayton cycle, in a reverse way of the magnetocaloric refrigerators. [8] Experiments have produced only extremely inefficient working prototypes, [ 9 ] [ 10 ] [ 11 ] however, thermodynamic analysis indicate that thermomagnetic motors present high efficiency related to Carnot efficiency for small temperature ...

  9. Infrared heater - Wikipedia

    en.wikipedia.org/wiki/Infrared_heater

    An infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm.
