  2. Ignition magneto - Wikipedia

    en.wikipedia.org/wiki/Ignition_magneto

    Magneto components. Impulse coupling components. An ignition magneto (also called a high-tension magneto) is an older type of ignition system used in spark-ignition engines (such as petrol engines). It uses a magneto and a transformer to make pulses of high voltage for the spark plugs. The older term "high-tension" means "high-voltage". [1]

  3. Magnetohydrodynamic generator - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_generator

    Diagram of a disk MHD generator showing current flows. The third and, currently, the most efficient design is the Hall effect disc generator. This design currently holds the efficiency and energy density records for MHD generation. A disc generator has fluid flowing between the center of a disc, and a duct wrapped around the edge.

  4. Wright R-3350 Duplex-Cyclone - Wikipedia

    en.wikipedia.org/wiki/Wright_R-3350_Duplex-Cyclone

    A Wright R-3350 radial engine, showing, R to L, propeller shaft, reduction gearcase, magneto (silver) with wiring, two cylinders (rear with connecting rod), impellor casing (and induction pipe outlets) and injection carburetor (black); separate accessory gearbox at extreme left. Data from Jane's. [9]

  5. Magnetohydrodynamic drive - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_drive

    Yamato 1 on display in Kobe, Japan.The first working full-scale MHD ship. A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics.

  6. Ignition system - Wikipedia

    en.wikipedia.org/wiki/Ignition_system

    As batteries became more common in cars (due to the increased usage of electric starter motors), magneto systems were replaced by systems using an induction coil.The 1886 Benz Patent-Motorwagen and the 1908 Ford Model T used a trembler coil ignition system, whereby the trembler interrupted the current through the coil and caused a rapid series of sparks during each firing.

  7. Telephone magneto - Wikipedia

    en.wikipedia.org/wiki/Telephone_magneto

    A telephone magneto is a hand-cranked electrical generator that uses permanent magnets to produce alternating current from a rotating armature. In early telegraphy , magnetos were used to power instruments, while in telephony they were used to generate electrical current to drive electromechanical ringers in telephone sets and activate signals ...

  8. Magneto - Wikipedia

    The magneto also had a medical application for treatment of mental illness in the beginnings of electromedicine. In 1850, Duchenne de Boulogne , a French doctor, developed and manufactured a magneto with a variable outer voltage and frequency, through varying revolutions by hand or varying the inductance of the two coils, for clinical ...

  9. Vibrating-sample magnetometer - Wikipedia

    en.wikipedia.org/wiki/Vibrating-sample_magnetometer

    VSM schematic VSM setup. A vibrating-sample magnetometer (VSM) (also referred to as a Foner magnetometer) is a scientific instrument that measures magnetic properties based on Faraday’s Law of Induction. Simon Foner at MIT Lincoln Laboratory invented VSM in 1955 and reported it in 1959. [1]
