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....
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 ...
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 Variations on the Aharonov-Bohm effect Three variations of the usual two...
whereΦAΦAis the flux of the magnetic field through some area and∂A∂Ais the closed loop boundary around that area. For this problem let's take "out of the page" to be the positive direction. Then the wire loop is a boundary enclosing a particular area throu...
To achieve coordinated functions, fluidic soft robots typically rely on multiple input lines for the independent inflation and deflation of each actuator. Fluidic actuators are controlled by rigid electronic pneumatic valves, restricting the mobility and
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 ...
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
A revision of the Dungey circulation model that describes the magnetospheric substorm process was introduced by Hones (1977). In this revision, magnetic flux transferred from the dayside builds up in the magnetotail during an interval when there is dayside reconnection and no reconnection in the near...
Relative motion of the magnetic field (which is assumed as co-rotating) compared to the circuit. Full size image The same argument can not only be made for case 6 in CCW rotation (field and closing wire spinning CCW is the same as the disc spinning CW in a stationary field), but the...
