2. Earth inductor compass - Wikipedia

   en.wikipedia.org/wiki/Earth_inductor_compass

   The anemometer of the earth inductor compass on the Spirit of St. Louis shows as a small "T" shape above the fuselage behind the wing. The Earth inductor compass (or simply induction compass [1]) is a compass that determines directions using the principle of electromagnetic induction, with the Earth's magnetic field acting as the induction field for an electric generator. [2]

3. Fluxgate compass - Wikipedia

   en.wikipedia.org/wiki/Fluxgate_compass

   A fluxgate inclinometer/compass. The basic fluxgate compass is a simple electromagnetic device that employs two or more small coils of wire around a core of highly permeable magnetic material, to directly sense the direction of the horizontal component of the Earth's magnetic field.

4. Explosive-driven ferromagnetic generator - Wikipedia

   en.wikipedia.org/wiki/Explosive-driven...

   An explosive-driven ferromagnetic generator (EDFMG, explosively pumped ferromagnetic generator, EPFMG, or FMG) is a compact pulsed power generator, a device used for generation of short high-voltage high-current pulse by releasing energy stored in a permanent magnet. It is suited for delivering high-current pulses (kiloamperes) to low-impedance ...

5. Compass - Wikipedia

   en.wikipedia.org/wiki/Compass

   A modern military compass, with included sight device for aligning. A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north.

6. Heading indicator - Wikipedia

   en.wikipedia.org/wiki/Heading_indicator

   Some more expensive heading indicators are "slaved" to a magnetic sensor, called a flux gate. The flux gate continuously senses the Earth's magnetic field, and a servo mechanism constantly corrects the heading indicator. [4] These "slaved gyros" reduce pilot workload by eliminating the need for manual realignment every ten to fifteen minutes.

8. Magnetohydrodynamic generator - Wikipedia

   en.wikipedia.org/wiki/Magnetohydrodynamic_generator

   The generator can also experience losses from the Hall effect current, which makes the Faraday duct inefficient. [citation needed] Most further refinements of MHD generators have tried to solve this problem. The optimal magnetic field on duct-shaped MHD generators is a sort of saddle shape.
