2. Permanent magnet synchronous generator - Wikipedia

   en.wikipedia.org/wiki/Permanent_magnet...

   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.

3. Drum memory - Wikipedia

   en.wikipedia.org/wiki/Drum_memory

   Drum memory was a magnetic data storage device invented by Gustav Tauschek in 1932 in Austria. [1] [2] Drums were widely used in the 1950s and into the 1960s as computer memory. Many early computers, called drum computers or drum machines, used drum memory as the main working memory of the computer. [3]

4. Magneto - Wikipedia

   Commutator of the Woolrich Electrical Generator. The first electrical machine used for an industrial process was a magneto, the Woolrich Electrical Generator. [3] In 1842 John Stephen Woolrich was granted UK patent 9431 for the use of an electrical generator in electroplating, rather than batteries.

5. Excitation (magnetic) - Wikipedia

   en.wikipedia.org/wiki/Excitation_(magnetic)

   An electric generator or electric motor consists of a rotor spinning in a magnetic field. The magnetic field may be produced by permanent magnets or by field coils . In the case of a machine with field coils, a current must flow in the coils to generate ( excite ) the field, otherwise no power is transferred to or from the rotor.

6. Magnetohydrodynamic generator - Wikipedia

   First, they cause simple parallel field lines. Second, because the fluid is processed in a disk, the magnet can be closer to the fluid, and in this geometry, magnetic field strengths increase as the 7th power of distance. Finally, the generator is compact, so the magnet is smaller and uses a much smaller percentage of the generated power.

   Nytavia Ragsdale, 26, and Laron Modlin, 25, are facing murder charges after their 4-year-old son Jah’Meik Modlin starved to death in a New York City apartment

8. Electric generator - Wikipedia

   en.wikipedia.org/wiki/Electric_generator

   The magnetic field of the dynamo or alternator can be provided by either wire windings called field coils or permanent magnets. Electrically-excited generators include an excitation system to produce the field flux. A generator using permanent magnets (PMs) is sometimes called a magneto, or a permanent magnet synchronous generator (PMSG).
