In a solid the spins of many electrons can act together to affect the magnetic and electronic properties of a material, for example endowing it with a permanent magnetic moment as in a ferromagnet.
22.
The permanent magnetic preloaded air-bearing guidance system may be used for many types of hanging transportation movements as well as for many other applications, such as for instance for the stick-slip-free positioning of components during assembly.
23.
When a magnetic field is absent the material has spontaneous magnetization which is a result of the ordered magnetic moments; that is, for ferromagnetism, the atoms are symmetrical and aligned in the same direction creating a permanent magnetic field.
24.
However, due to lack of control over the specific transformations involved in the formation of the particles, truly superparamagnetic particles have not yet been prepared from magnetite, i . e . magnetite nanoparticles that completely lose their permanent magnetic characteristic in the absence of an external magnetic field ( which by definition show a coercivity of 0 A / m ).
25.
Undulators only became practical devices for insertion in synchrotron light sources in 1981, when teams at the Lawrence Berkeley National Laboratory ( LBNL ), Stanford Synchrotron Radiation Laboratory ( SSRL ), and at Budker Institute of Nuclear Physics ( BINP ) in Russia developed permanent magnetic arrays, known as Halbach arrays, which allowed short repeating periods unachievable with either electromagnetic coils or superconducting coils.
26.
Goldwind USA has sold close to 300 MW of permanent magnetic direct drive ( PMDD ) turbines, with the Compton, Illinois-based Shady Oaks project serving as its largest utility scale wind farm at 109.5MW . Goldwind USA works with US-based suppliers including North Dakota's LM Wind Power, the Timken Company in Ohio, Maxwell Technologies in California and Broadwind Energy in Wisconsin among many others.
