Earth’s magnetic field perturbed by 'electric oceans', claims researcher（图）
Earth’s magnetic field electric oceans electric sea salts
2009/6/15
In a radical rethink of accepted geophysics, new research in the US links variations in the Earth’s magnetic field with the ebb and flow of the world’s oceans. Given the practical importance of these ...

The Cosmic Ray Asymptotic Directions for Station Oulu in the Magnetic Field of the Tsyganenko 1989 Model
cosmic rays magnetospheric magnetic field asymptotic directions geomagnetic disturbance level
2009/6/10
Using the magnetospheric field model developed by Tsyganenko (1989) the asymptotic directions
were calculated for cosmic ray particles entering the top of the atmosphere at Oulu (65.°06N, 25.°47E).Th...

Collapse and fragmentation models of cloud cores with magnetic field support。
We present results on the magnetic field topology in a pulsed radiative jet.For initially helical magnetic fields and perio dic velo city variations, we find thatthe magnetic field alternates along th...
The Heliospheric Magnetic Field over the Hale Cycle
Heliospheric Magnetic Field Hale Cycle coronal mass ejections
2009/5/27
The concept that open magnetic flux of the Sun (rooted with one and only one footpoint at the Sun) is a conserved quantity is taking root in the heliospheric community. Observations show that the Sun'...
Small-scale Magnetic Field Diagnostics outside Sunspots：Comparison of Different Methods
Sun magnetic fluxtubes kG magnetic fields
2009/5/12
We analyse different observational data related to the problem
of intrinsic magnetic field strength in small-scale fluxtubes outside
sunspots. We conclude that the kG range of fluxtube fields follow...
Effect of Interplanetary Magnetic Field and Disturb Storm Time on H Component
Sudden Storm Commencement (SSC) magnitude of the H component deviation Interplanetary Magnetic Field (IMF)
2009/5/6
A fluxgate digital magnetometer is used to study the variation
of magnitude of H component during geomagnetic storm events of
April, July and November 2004 at southern subauroral localized region at...
Seismic Study of Magnetic Field in the Solar Interior
Sun oscillations interior magnetic field
2009/5/6
Magnetic field in the solar interior contributes to the even order
splitting coefficients, but it is not possible to separate the effect of magnetic
field from those due to other deviations from sph...
The Evolution of Vector Magnetic Field Associated with Major Flares in NOAA AR10656
Magnetic field evolution flares
2009/5/6
In this paper, we study the evolution of vector magnetic
field of AR 10656 by using the observations of Huairou Solar Observing
Station (HSOS, China) and Big Bear Solar Observatory (BBSO, USA).

Study of the Polymerization of Methyl Methacrylate Initiated by Thioxanthone Derivatives: A Magnetic Field Effect
Mag0netic field effect polymerization photoinitiator thioxanthone one-component initiator
2010/4/9
Free radical photopolymerization of methyl methacrylate (MMA) initiated by 2-mercaptothioxanthone (TX-SH), thioxanthone-thioacetic acid (TXSCH2COOH), and thioxanthone-carboxymethoxy acetic acid (TXOCH...
Multipolar dance could flip Earth’s magnetic field（图）
Multipolar dance Earth’s magnetic field the Earth’s magnetic poles
2009/5/4
In this new proposal, it is not the turbulent flow but a second field known as a “quadrupole” that drives the reversal. Leading up to the flipping of the poles, the dipole reduces in intensity as the ...
