2. Magnetohydrodynamic generator - Wikipedia

   en.wikipedia.org/wiki/Magnetohydrodynamic_generator

   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.

3. 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 ...

   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.

6. Magnetohydrodynamics - Wikipedia

   en.wikipedia.org/wiki/Magnetohydrodynamics

   The liquid outer core moves in the presence of the magnetic field and eddies are set up into the same due to the Coriolis effect. [18] These eddies develop a magnetic field which boosts Earth's original magnetic field—a process which is self-sustaining and is called the geomagnetic dynamo. [19] Reversals of Earth's magnetic field

8. Magnetohydrodynamic converter - Wikipedia

   en.wikipedia.org/wiki/Magnetohydrodynamic_converter

   A magnetohydrodynamic generator is an MHD converter that transforms the kinetic energy of an electrically conductive fluid, in motion with respect to a steady magnetic field, into electricity. MHD power generation has been tested extensively in the 1960s with liquid metals and plasmas as working fluids. [7]
