Low temperature measurements show a hard magnetic behavior and the presence of exchange-bias effect after field cooling to 2 K. The results obtained in this study prove essential for the development of flexible electronics.Similar content being viewed by others Phase transition and electrical ...
Therefore, current high-resolution observational data support the results of this study by means of case analyses. These observations have also been explained theoretically7. The sun is magnetic, and its magnetic field elements can be classified into 5 groups according to their magnetic flux content...
What is B in a solenoid with 100 turns in 10 cm, and current 0.1 A? The field is 125 mT. To calculate the magnetic field inside this solenoid, simply apply the formula: B = µ0 · N · I/L, And substitute the following values: N = 100; L = 0.1 m; and I = 0.1 A. The...
The fundamental difficulty faced by any statistical description of turbulence is the statistical closure problem,8 in which the time evolution of cumulants (defined in Section 3.5.2) of order n for some field ψ is coupled by the nonlinearity to cumulants of order n+1. For example, if the ...
This paper gives dispersion curves derived from the Appleton-Hartree formula in the case of zero absorption. The value of the magnetic field is taken as that of the earth's field at Slough. The curves are drawn to show the value of the squares of the indices of refraction and attenuation ...
In very general terms, magnetic susceptibility measurements tell you how your material responds to an applied magnetic field, which can be used to unveil the magnetic identity of your material. Susceptibility measurements can be performed in a direct current (DC) field, giving insights on the ...
A completely new way of using superconducting magnet technology to confine plasma with high energy and extremely high temperatures is proposed. Using the PIC method of microscopic particle simulation, the plasma magnetic nozzle effect and performance of the MPDT under different magnetic-field conditions...
