Sentences with phrase «magnetic dipole field»

Hale suggested that the sunspot cycle period is 22 years, covering two polar reversals of the solar magnetic dipole field... The start of the 22 - year cycle begins... This process of sunspot formation and migration continues until the solar dipole field reverses (after about 11 years).

If space were a vacuum, then the Sun's 10 - 4 tesla magnetic dipole field would reduce with the cube of the distance to about 10 - 11 tesla.

Not exact matches

The research team rearranged the two dipole coils from a parallel position to cross them in order to generate rotating magnetic fields, which was embedded in the Tx's flat platform.

The research team used the Dipole Coil Resonance System (DCRS) to induce magnetic fields, which was developed by the team in 2014 for inductive power transfer over an extended distance.

This chain acts as a permanent dipole magnet and is able to passively reorient the whole bacteria along the Earth's magnetic field lines.

The farther away from Earth you get, the more its magnetic field actually does act like a dipole, or a bar magnet — even if in reality it is no such thing.

Earth's dipole magnetic field strength has decreased 16 percent since 1840 — with most of the decay related to the weakening field in the South Atlantic Anomaly — leading to much speculation that the planet is in the early stages of a field reversal.

A unique property of the molecule is the large permanent dipole moment, which reacts with an electric field much like a bar magnet reacts with a magnetic field.

Paul realized that it is possible to design a magnetic field with a local minimum in the field strength, and if the magnetic dipole is originally aligned to seek a position where the field is weakest, it will remain aligned in the «weak field - seeking» orientation [see «Cooling and Trapping Atoms,» by W. D. Phillips and H.].

Professor Rim proposed a meaningful solution to these problems through DCRS, an optimally designed coil structure that has two magnetic dipole coils, a primary one to induce a magnetic field and a secondary to receive electric power.

«We think we've got a much more complicated magnetic field than the simple magnetic dipole model.»

During its January 2008 flyby, NASA's MESSENGER spacecraft detected an internal magnetic field consistent with the field from a dipole nearly aligned with the planet's spin axis (with a dipole tilt around 10 °).

hengav (00:25:44): What I became alarmed at were graphs like: http://www.ngdc.noaa.gov/stp/GEOMAG/image/aastar07.jpg There are three factors that contribute to the trends seen in the Figures you cite: (1) the aa - index is too low before 1957, see http://www.leif.org/research/Analysis%20of%20K=0%20and%201%20for%20aa%20and%20NGK.pdf (2) the sunspot number is too low before 1946, see http://www.leif.org/research/De%20maculis%20in%20Sole%20observatis.pdf (3) the Earth's dipole magnetic field has decreased 10 % the last 150 years.

I could go into endless detail about how charged particles in an electric or magnetic field radiate; about how electromagnetic radiation has electric and magnetic fields; about how atoms and molecules in collision form electric dipoles and undergo charge separation.

«The dipole and quadrupole components of the solar magnetic field change in relative amplitude and phase.»

In the Sun, surface differential rotation changes on a centennial time scale coincide with the observed phase change between the toroidal and poloidal magnetic field components and the time dependence of the dipole and quadrupole components of the poloidal magnetic field (Feynman & Ruzmaikin, 2014).

Here, we aim to summarise present knowledge about the Holocene magnetic field evolution and remaining uncertainties, mainly concentrating on the dipole contribution and only briefly mentioning progress in describing regional differences in field intensity.

Similarly, VGPs are obtained as the poles of a pure, but tilted, dipole field from magnetic directional results.
