A magnetohydrodynamic generator (MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity. An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current.
Over 60 years, JEGS has expanded to include a 250,000-square-foot (23,000 m 2) warehouse, two mail order locations, retail store & Team JEGS Race Team. The company has approximately 350 employees. The company has approximately 350 employees.
[8] [7]: 25 The connection between the fluid and magnetic field fixes the topology of the magnetic field in the fluid—for example, if a set of magnetic field lines are tied into a knot, then they will remain so as long as the fluid has negligible resistivity. This difficulty in reconnecting magnetic field lines makes it possible to store ...
The MK-2 generator is particularly interesting for the production of intense currents, up to 10 8 A (100 MA), as well as a very high energy magnetic field, as up to 20% of the explosive energy can be converted to magnetic energy, and the field strength can attain 2 × 10 6 gauss (200 T).
These systems operate in a magnetic Brayton cycle, in a reverse way of the magnetocaloric refrigerators. [8] Experiments have produced only extremely inefficient working prototypes, [ 9 ] [ 10 ] [ 11 ] however, thermodynamic analysis indicate that thermomagnetic motors present high efficiency related to Carnot efficiency for small temperature ...
The free-piston engine linear generators can be divided in 3 subsystems: [1] [2] One (or more) reaction section with a single or two opposite pistons; One (or more) linear electric generator, which is composed of a static part (the stator) and a moving part (the magnets) connected to the connection rod.
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.
First ideas of a magnetic motor were put forward by Petrus Peregrinus de Maricourt in 1269, who imagined a toothed wheel that is continually moving by the force of magnets. [ 4 ] [ 5 ] A popular example of a magnet motor, although without rotating axis, was put forward by John Wilkins in 1670: A ramp with a magnet at the top, which pulled a ...
