  2. Mechanically powered flashlight - Wikipedia

    en.wikipedia.org/wiki/Mechanically_powered...

    A dyno torch, dynamo torch, or squeeze flashlight is a flashlight or pocket torch which generates energy via a flywheel. The user repeatedly squeezes a handle to spin a flywheel inside the flashlight, attached to a small generator/dynamo, supplying electric current to an incandescent bulb or light-emitting diode. The flashlight must be pumped ...

    Fig. 2. The construction of Inductively Coupled Plasma torch. [3] A: cooling gas tangential flow to the outer quartz tube B: discharge gas flow (usually Ar) C: flow of carrier gas with sample D: induction coil which forms the strong magnetic field inside the torch E: force vectors of the magnetic field F: the plasma torch (the discharge).

  4. Induction plasma torch - Wikipedia

    en.wikipedia.org/wiki/Induction_plasma

    The technology is applied via an Induction plasma torch, which consists of three basic elements: the induction coil, a confinement chamber, and a torch head, or gas distributor. The main benefit of this technology is the elimination of electrodes, which can deteriorate and introduce contamination.

  5. Flashlight - Wikipedia

    en.wikipedia.org/wiki/Flashlight

    A flashlight or electric torch (Commonwealth English), usually shortened to torch, is a portable hand-held electric lamp. Formerly, the light source typically was a miniature incandescent light bulb , but these have been displaced by light-emitting diodes (LEDs) since the early 2000s.

  6. 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 ...

    A fusion torch is a technique for utilizing the high-temperature plasma of a fusion reactor to break apart other materials ... a doughnut-shaped magnetic "bottle ...

  8. Inductively coupled plasma atomic emission spectroscopy

    en.wikipedia.org/wiki/Inductively_coupled_plasma...

    The torch is operated in the H mode. When the torch is turned on, an intense electromagnetic field is created within the coil by the high power radio frequency signal flowing in the coil. This RF signal is created by the RF generator which is, effectively, a high power radio transmitter driving the "work coil" the same way a typical radio ...

  9. Magnetorquer - Wikipedia

    en.wikipedia.org/wiki/Magnetorquer

    A magnetorquer or magnetic torquer (also known as a torque rod) is a satellite system for attitude control, detumbling, and stabilization built from electromagnetic coils. The magnetorquer creates a magnetic dipole that interfaces with an ambient magnetic field, usually Earth's , so that the counter-forces produced provide useful torque .
