  2. Birkeland current - Wikipedia

    en.wikipedia.org/wiki/Birkeland_current

    Schematic of the Birkeland or Field-Aligned Currents and the ionospheric current systems they connect to, Pedersen and Hall currents. [1]A Birkeland current (also known as field-aligned current, FAC) is a set of electrical currents that flow along geomagnetic field lines connecting the Earth's magnetosphere to the Earth's high latitude ionosphere.

  3. Thermal cutoff - Wikipedia

    en.wikipedia.org/wiki/Thermal_cutoff

    A thermal switch (sometimes thermal reset or thermal cutout (TCO)) is a device which normally opens at a high temperature (often with a faint "plink" sound) and re-closes when the temperature drops. The thermal switch may be a bimetallic strip, often encased in a tubular glass bulb to protect it from dust or short circuit. Another common design ...

  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. Limit switch - Wikipedia

    en.wikipedia.org/wiki/Limit_switch

    In electrical engineering, a limit switch is a switch operated by the motion of a machine part or the presence of an object. A limit switch can be used for controlling machinery as part of a control system , as a safety interlock , or as a counter enumerating objects passing a point.

  6. OpenTherm - Wikipedia

    en.wikipedia.org/wiki/OpenTherm

    OpenTherm (OT) is a standard communications protocol used in central heating systems for the communication between a central heating appliances and a thermostatic controller. [1] As a standard, OpenTherm is independent of any single manufacturer. A controller from manufacturer A can in principle be used to control a boiler from manufacturer B ...

  7. Earth's magnetic field - Wikipedia

    en.wikipedia.org/wiki/Earth's_magnetic_field

    This current reduces the magnetic field at the Earth's surface. [27] Particles that penetrate the ionosphere and collide with the atoms there give rise to the lights of the aurorae while also emitting X-rays. [28] The varying conditions in the magnetosphere, known as space weather, are largely driven by solar

  8. Air preheater - Wikipedia

    en.wikipedia.org/wiki/Air_preheater

    The heating plate elements in this type of regenerative air preheater are also installed in a casing, but the heating plate elements are stationary rather than rotating. Instead the air ducts in the preheater are rotated so as to alternatively expose sections of the heating plate elements to the upflowing cool air. [1] [2] [3]

  9. Critical field - Wikipedia

    en.wikipedia.org/wiki/Critical_field

    The upper critical field is the magnetic flux density (usually expressed with the unit tesla (T)) that completely suppresses superconductivity in a type-II superconductor at 0 K (absolute zero). More properly, the upper critical field is a function of temperature (and pressure) and if these are not specified, absolute zero and standard pressure ...
