Skyrmion motion driven by oscillating magnetic field 2012-6-15 a magnetic skyrmion is a topological spin texture of which the spins wrap around a unit sphere 1234a well-known example of skyrmion system is the chiral magnets in skyrmion crystal materials 45recently skyrmion control has been drawing much attention because of its use in noble spin devices as well as an unexpected.
Details2019-11-10this omf oscillating magnetic field generator produces a decaying strength bi-polar series of pulses that have a frequency close to 7000 hertz cycles per secondclick here for the background medical research for this device similar multiple oscillating pulse outputs were described in patent 4524079 as being effective against bacteria and fungus in lab.
DetailsIn order to excite the spin wave modes and create skyrmions and skyrmioniums we have used an oscillating perpendicular magnetic field b z b 0 sin 2 ft where b 0 is the magnetic field intensity and f is the frequency of the spin wave modes obtained from the curve.
DetailsPreviously it has been shown that long-distance migrants garden warblers sylvia borin were disoriented in the presence of narrow-band oscillating magnetic field 1403 mhz omf 190 nt during autumn migrationthis agrees with the data of previous experiments with european robins erithacus rubeculain this study we report the results of experiments with garden warblers tested under a 1.
Details2020-4-17as you point out an oscillating electric charge and by that i assume you mean a charge moving back and forth generates both an oscillating electric field but also an oscillating magnetic field this is straight forward to understand from the fact that charge in motion produces a magnetic.

DetailsThe application of oscillating magnetic field pulses might be used in disinfecting agricultural products and food view show abstract biological effects of magnetic fields studies with.
Details2011-3-31motion in oscillating fields we have seen that charged particles can be confined by a static magnetic field a somewhat more surprising fact is that charged particles can also be confined by a rapidly oscillating inhomogeneous electromagnetic wave-field in order to demonstrate this we again make use of our averaging.
DetailsHere we describe an mri technique that uses oscillating magnetic field gradients to significantly amplify and detect the lorentz effect induced by neuroelectric activity and we demonstrate its effectiveness in imaging sensory nerve activation in vivo in the human.
DetailsMaterial having relatively high electrical resistivity such as food products and containers is disposed within a magnetic coil and subjected to one or more pulses of an oscillating magnetic field having an intensity of between about 2 and about 100 tesla and a frequency of between about 5 and about 500 khz a single pulse of the magnetic field generally decreases the microorganism population.
DetailsThe oscillatory current flowing in the coil produces an oscillating magnetic field in the case of homogeneous broadening only one mode can normally oscillate.
