In ferrimagnetic materials, the spontaneous arrangement is a combination of both patterns, usually involving two different magnetic atoms, so that only partial reinforcement of magnetic fields occurs.
Flares are not completely understood, but are believed to be caused by strong magnetic fields, which suppress plasma convection and lead to sudden outbursts: strong magnetic fields occur in rapidly rotating stars, while old stars tend to rotate slowly.
Finally, there were two source dipoles explaining the magnetic fields occurring over the left and right fronto-temporal regions.
(In addition, exposure to extremely low-frequency magnetic fields occurs from battery discharge).
It had generally been difficult to utilize a magnetic field for tailoring the microstructure in feeble magnetic ceramics, such as Al2O3; however, the possibility of controlling the microstructure by a magnetic field occurred with the development of superconducting magnets.
It had generally been difficult to utilize a magnetic field for controlling the texture of diamagnetic ceramics because of their extremely small susceptibility; however, the possibility of controlling the texture by a magnetic field occurred with the development of superconducting magnets.
The definitive discovery of the Jovian magnetic field occurred in December 1973, when the Pioneer 10 spacecraft flew near the planet.
This capability probably helps the creatures navigate –but it could also allow them to sense earthquakes before they strike.Since the late 1990s, it has been known that fluctuations in the Earth's magnetic field occur before some earthquakes.
As a consequence, instabilities in the plasma motion and magnetic field occur.
Magnetoplasmons are collective excitations of electron gas in magnetic field, occurring as poles of density-to-density response function.
No dependence on the axial position is observed and no difference between the measurement inside and outside the magnetic field occurs.
