Here the new MR imaging technique without the magnet is proposed. Instead of the magnet it uses the earth's magnetic field. The results of the preliminary experiments make possible to reconstruct the NMR images of fantoms without using an radiofrequency shielding.StepinikErenMihailovi...
The only possible source of the zenith angle dependence of the numbers of atmospheric neutrino events is the magnetic field of the earth. At energies higher than 1 GeV the effect of the magnetic field of the earth is low and the numbers of down-going and up-going νμ (νe) (if there...
sea floor. At the mid-ocean ridge, magma rises up from the mantle below and cools. As it continues to cool, iron in the rock aligns itself with the magnetic field of the Earth, much like the needle in a compass. When the rock solidifies, this magnetic “signature” is locked in ...
Now, the other navigation system for the mole rat relies on Earth's magnetic field. Mole rats have the ability to sense the magnetic field and use it to orient themselves directionally. But until recently scientists weren't sure about the role of these two different systems. Recently a team...

The equatorial ring current and the magnetopause current both contribute to the magnetic field at low altitudes over the polar cap. In this region the magnetic field is dominated by the Earth's internal field and is well described by empirical models. The average change in the magnetic field ...
An Automatic Instrument to Measure the Absolute Components of the Earth's Magnetic Field H.-U. Auster, M. Mandea, A. Hemshorn, E. Pulz, M. Korte. SMART About NASA’s Magnetospheric Multiscale Mission (MMS) MAGNETIC RECONNECTION is a little-understood physical process at the heart of spac...
a magnet is placed with its poles aligned at a right angle to the compass. The deflection angle of the needle is noted for varying distances of the magnet, and with some quick math the local field strength of the Earth’s magnetic field can be calculated based on the strength of the mag...
An Experiment on the Origin of the Earth's Magnetic Field Of the many suggestions which have been made as to the origin of the earth's magnetic field, perhaps the most promising is that it may be due to a slight m... H Wilson - 《Proceedings of the Royal Society A Mathematical Physic...
Every day space telescopes provide spectacular images of the solar activity. However, their instruments are blind to its main driver: the magnetic field in the outer layers of the solar atmosphere, where the explosive events that occasionally affect the Earth occur. The extraordinary observation...
