Based on the almost fibril state of magnetic flux in astrophysical bodies we present a study of the stability of magnetic flux tubes which are described by the thin flux tube approximation. A stationary flow is allowed in the tube which in equilibrium lies in a vertical plane, while the ...
Stationary siphon flows in arched magnetic flux tubes are studied. A pressure difference between the two footpoints of the tubes, which are anchored below the solar surface, drives the flow along the tubes. The radiative heat exchange between the tube and its surroundings is taken into account....
A parameter of this field is the magnetic flux density. In the first step, the relationship between magnetic flux density and the force exerted on a conductor through which current flows is derived. Furthermore, it is shown that a voltage will be generated at the ends of a conductor loop ...
When an electric charge passes past a stationary current loop the time-varying fields induce changes of the internal energy of the loop. The magnetic flux ... G Spavieri,G Cavalleri - 《Epl》 被引量: 13发表: 1992年 Aharonov–Bohm effect in the Abelian-projected SU(3)-QCD with Θ-term...
In this paper, we proposed a sliding mode control method for the bearingless permanent magnet slice motor for the blood pump based on the genetic particle swarm algorithm, which aims to solve the problems of strong coupling, strong interference, nonlinea
We show that the loop curvature statistics become stationary through a dynamical formation process of high-curvature folds, leading to distributions with power-law tails whose exponents are determined by the large-deviations statistics of finite-time Lyapunov exponents of the flow. This prediction ...
Therefore, each magnet self sustains its respective electromagnetic loads: the TFC are D-shaped to minimize in-plane bending moments [2] and their inboard straight legs are closed together by the centripetal load, setting up a ring; the CS stack sustains its radial expansion load through a ...
This is achieved by subtracting the time-synchron‐ ized signal, recorded at a stationary base magnetometer, from survey data. Alternatively, points of intersection of tie lines with traverse/profile lines can form loop networks which can be used to correct for the diurnal variation similar to ...
Here we show through multi-spacecraft observations, global simulations, and analytic theory that the lowest-frequency impulsively-excited magnetopause surface waves, with standing structure along the terrestrial magnetic field, propagate against the flow outside the boundary. Across a wide local time ...
Specifically, the bipolar coil generates a magnetic field that travels from one side of the coil to the other, with the magnetic flux circulating between the two sides of the coil, forming a complete loop. Φin−p is the magnetic flux passing through Lin from Lp, then Φp−in is the...
