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.

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 ...
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.
The 1200-ton motor generator sits on a 4800-short ton (4350 t) inertia block which rests on 60 springs to minimize earth tremors and is the centerpiece of the Pulsed Field Laboratory. The facility's magnets include a 60 Tesla long-pulse magnet (under repair) that is the most powerful controlled-pulse magnet in the world.
Exposure to strong magnets, or magnetic interference can sometimes cause the magnetic poles of the compass needle to differ or even reverse. Avoid iron rich deposits when using a compass, for example, certain rocks which contain magnetic minerals, like Magnetite. This is often indicated by a rock with a surface which is dark and has a metallic ...

Three years after the original suspect in a nearly 40-year-old double murder was exonerated based on DNA evidence and freed from prison after 20 years, a Georgia man has been arrested and charged ...
A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.
