Maxwell's equations and the critical state-Bean model are used to analytically determine the magnetic flux density and electromagnetic force distributions in superconducting tapes containing central and edge ob
Lorentz force refers to the force applied to elements of a fluid with electrical conductivity when it flows in a duct under an external electrical and magnetic field. It affects the velocity magnitude and temperature field in thermal equipment. ...
From this equation, the following points can be made: (a) Relationships between the radial forces and suspension winding currents are modulated by the revolving motor magnetic field. (b) The radial forces are proportional to the motor excitation current I4. (c) The radial forces are proportional...
the sperm medium (SP-TALP) was set as a Newtonian fluid with the density of 103 kg m−3and viscosity of 1 mPa s. During finite element analysis, the applied load was given as a function of the magnetic torque in the local coordinate system. The magnetic torqueTmwas calculated...
The structure moves under the action of the electrostatic and/or magnetic driving, and the movement is sensed by the sense electrode. Full size image In order to sustain the oscillation when\(\vec{B}=0\), or simply to characterize the device, an electrostatic driving is applied between the...
The structure and dynamics of the solar corona is dominated by the magnetic field. In most areas in the corona magnetic forces are so dominant that all non
(1)) to the magnetization and magnetic flux density. Fig. 2 shows our proposed Amperian current loop model to represent the magnetization of a differential element. The differential element is large enough so that there are many microscopic dipole current loops contained within the element (a)....
Electromotive force refers to the force that drives the flow of electric current in a circuit, which is proportional to the rate of change of magnetic flux. AI generated definition based on: Methods in Geochemistry and Geophysics, 2003
The attractive force of the electromagnets may be characterized by the following equation: ##EQU1## Where B=flux density, A=cross-sectional area and μ0=magnetic permeability of free space. The total force of attraction may be considered as the sum of the attraction between the laminated and...
B=Magnetic flux density K=Constant Using equation 1, the net force on the armature of a force motor when the coils are energized can be calculated as follows:1Ffm=K{(Bp+Bi)2-(Bp-Bi)2}=4 KBpBi Eqn. 2 ...
