In 1930, physicists Werner Heisenberg and Hans Heinrich Euler predicted that very strong magnetic fields could change the polarity of light waves in a vacuum (where polarity refers to the orientation of the light's electric and magnetic fields).

If you provide energy in the form of radio waves, these tiny magnets can switch orientation and give off a resonance frequency that changes predictably based on the strength of the magnetic field.

Indeed, the experiments revealed that the magnetic field orientation of the magnetosomes is not directed along the chain direction, as assumed up to now, but is slightly tilted.

A geomagnetic reversal is a change in the orientation of Earth's magnetic field such that the positions of magnetic north and magnetic south become interchanged.

The direction of the magnetic field — the north / south orientation — depends on the direction of the flow of the electricity.

Typically, when solar structures with opposite magnetic orientations collide, they explosively release magnetic energy, heating the atmosphere with a flare and erupting into space as a coronal mass ejection — a massive cloud of solar material and magnetic fields.

By manipulating magnetic and electromagnetic fields, they flipped the electron's orientation, changing the vibration frequency of the cantilever.

Magnetic fields of different strengths make those electrons spiral in particular ways, and that spiraling changes the orientation of the light as it travels toward Earth.

Place a muon in a magnetic field perpendicular to the orientation of its magnetization, and its magnetic polarity will turn, or precess, just like a twirling compass needle.

Using a rotating magnetic field, the researchers were able to fabricate the ideal textured microstructure of the individual LiCoO2 grains making up the cathode: a perpendicular alignment of the c - plane (the vertical side) and a random orientation of the c - axis.

Those traces, which record the orientation of the samples relative to Earth's magnetic field when they solidified, can be used to determine where on the globe the rocks formed.

In their study, the ICFO team cooled down a cloud of atoms to a few micro-degrees Kelvin, applied a magnetic field to produce spin motion as in MRI, and illuminated the cloud with a laser to measure the orientation of the atomic spins.

If two colliding regions of plasma have the same density, temperature and strength (but different orientation) of their magnetic fields, symmetrical reconnection begins.

When two areas with plasma (electrically charged gas) and magnetic fields with different orientations collide, the magnetic fields can be «clipped off» and «reconnected» so that the topology of the magnetic field is changed.

The perception of Earth's magnetic field is used by many animal species for orientation and navigation.

If such a particle is placed in a magnetic field whose strength varies from region to region, it will move toward the weakest or strongest part of the field, depending on the particle's orientation [see illustration on next page].

Each 0 or 1 is encoded using the orientation of the atom's magnetic field.

In a study led by Alexander Pines, a senior faculty scientist with Berkeley Lab's Materials Sciences Division and UC Berkeley's Glenn T. Seaborg Professor of Chemistry, researchers recorded the first bulk room - temperature NMR hyperpolarization of carbon - 13 nuclei in diamond in situ at arbitrary magnetic fields and crystal orientations.

The research group of Alex Pines has recorded the first bulk room - temperature NMR hyperpolarization of carbon - 13 nuclei in diamond in situ at arbitrary magnetic fields and crystal orientations.

«We think it is possible to use a static magnetic field first to help guide the nanoparticles to the clot, then alternate the orientation of the field to increase the nanoparticles» efficiency in dissolving clots,» says Paolo Decuzzi, who led the study.

Our results show not only the magnetic field orientation of around young stellar objects but also the structure of circumstellar matter such as outflow regions and their parent molecular cloud along the line of sight.

Particularly the findings that already small fluctuations in Earth's magnetic field elicit a behavioral response and the fact that «normal» magnetic conditions under which dogs express their orientation behavior occur only in about 30 % of all cases call for caution.

The orientation of the twist of the magnetic field at low heights turned out to be the same as that of the flows below the solar surface for four of the six regions.

We furthermore suggested that Cluster N is likely to process such light - mediated magnetic compass responses, based on the fact that Cluster N is the only known forebrain area that is highly active during magnetic compass orientation, and on the theoretical model [7] on magnetic field modulation of the light sensitivity of specialized receptor molecules in the retina of the birds, [for detailed arguments see 13], [14].

However, if the Sun's magnetic field arrives at Earth with a certain orientation aurora can occur at higher latitudes, and the origin of these auroras are much less understood.
