Magnetic field, a vector field in the neighborhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to lin

at the same time as sunspot maximum—over the record shown, the flare activity maximum occurs several years post sunspot maximum. (c) Latitude–time distribution of the GOES flares ofb. (d) Latitude–time variation of the photospheric magnetic field at the central meridian. Note the strong ...
Here, the ferromagnetic properties are what have been created by strain, magnetic field, and temperature along with observation of the parallel magnetic domains in ferromagnetic graphene for the first time as a great achievement. In this way, we have represented the following: First, introducing ...
The total magnetic field at a given point x in the magnetic medium equals the sum of the head field Hh (x) and the demagnetization field Hd (x). H(x)=Hh(x)+Hd(x) As this field is applied to the M–H loop of the magnetic medium, described by the non-linear function M(H), ...

The weak magnetic field hadn’t always been that way: The team examined similar rocks from South Africa that dated back more than 2 billion years and found, at that point in time, the Earth’s magnetic field was as strong as it is today. ...
It presents substantial properties, such as biodegradability, biocompatibility, minimal toxicity, high magnetic susceptibility and superparamagnetism [9]. When a strong magnetic field is applied to a ferrofluid, magnetite particles become oriented in the direction of the field and become magnetized [8]....
In this case, the magnetic fields created by those spins point in opposite directions, so they cancel each other. However, some atoms contain one or more unpaired electrons, and these unpaired electrons create a tiny magnetic field. The direction of their spin determines the direction of the ...
Fig. 6: The magnetic-field orientation of the El Gordo cluster. The background emission image is from MeerKAT observation at 1.28 GHz (FWHM approximately 7″). The Synchrotron Intensity Gradient (SIG) measurement has a resolution of FWHM approximately 24″(or 400 kpc). Each white segment...
