or intense demagnetic effects of the film compared with the long cylinder-shaped superconductor, between the average values of field and magnetization there is a quantitative relation = μ[ H+(0.8 d/ R)] for a disk-shaped film and a qualitative relation =μ [H +/ 1+(2R/d) ] for an...
There is a simple relation between current helicity and the 伪 -effect. In the case of amplification of a mean magnetic field by the 伪 -effect (1) both fluctuating and mean magnetic fields possess current helicities, (2) the current helicities of fluctuating and mean magnetic fields have ...
The region surrounding the magnet in which the force of the magnet can be felt is called the extent of themagnetic field. Its SI unit is Tesla and it is named after the American Scientist Nikola Tesla. Gauss is the smaller unit of themagnetic field. Magnetic field lines generally originate ...

Current source models for the Earth's main geomagnetic field are calculated employing conventional discrete inverse theory methods. Source structures are spherical surfaces placed at the surface of the Earth's core, and at the surface of the Earth. The data set consists of measurements taken by ...
(a) I−V characteristics of a Pb0.6In0.4/Ba0.6K0.4(FeAs)2 point-contact Josephson junction, recorded in zero magnetic and zero microwave fields at different temperatures. (b) Symbols: measured normalized critical currents Ic(T)/Ic(0) as a function of the normalized temperature T/Tc for ...
1. Here we show 1/2-hour averages of the field components measured outside of the current sheet during the Pioneer, Voyager, and Ulysses passes, projected onto the magnetic equatorial plane. These data were supplied by the Planetary Data System at UCLA at 10 s resolution for Pioneer-11 ...

Geomagnetic disturbances (GMDs) are rapid fluctuations in the strength and direction of the magnetic field near the surface of the Earth which can cause electric currents to be induced in the ground. The geomagnetically induced currents (GICs) can cause damage to pipelines and power grids. A det...
These studies have yielded the following results: (1) The change in the total unsigned current in an AR is synchronous or quasi-synchronous with changes in the magnetic flux; (2) A relation between the total unsigned current and the flare index (FI) exists, but is weak (correlation k = ...
