Magnetic flux leakage (MFL) technique is one of the basic methods of non-destructive testing (NDT) used for the in-line inspection (ILI) of pipelines and other objects made from materials with high magnetic permeability [1-3]. The MFL method uses the fact that near a defect in an ...
The time-dependent Ginzburg-Landau equation is solved numerically for type-II superconductors of complex geometry using the finite element method. The geometry has a marked influence on the magnetic vortex distribution and the vortex dynamics. We have observed generation of giant vortices at boundary ...
I am interested in finding out if there is an equation that you can use to calculate the amount of 'current or voltage' produced in a single copper wire by knowing the 'strength' and 'speed' of a moving permanent magnetic field that is perpendicular to said wire. Application is that of...
The first two equations give the value of the given flux through a closed surface, and the second two equations give the value of a line integral around a loop. In this notation, ∇=(∂/∂x, ∂/∂y, ∂/∂z) E is the electric vector, B is the magnetic induction, ...

Torque in a three phase induction motor is determined by three key factors:Firstly the magnitude of rotor current, secondly the flux which interact with the rotor of three phase induction motor and is responsible for producing emf in the rotor part of in
Magnetic flux rope detection & reconstruction based on the extended Grad-Shafranov equation. Introduction This package consists of two key products to serve as a set of comprehensive tools for the investigation of magnetic flux ropes (FRs) in space plasmas based on in-situ spacecraft measurements....
Lenz’s law is based onFaraday’s law of electromagnetic induction. The combined equation for these two laws are: Where, N is the number of turns of coil, ΔΦ is the change in magnetic flux through the coil in time Δt. The minus sign indicates the opposition to the change in magneti...
To simplify the formulation, we will assume that the medium we are studying is nonferromagnetic (the study of the optical properties of magnetic semiconductors is the topic of a separate Chapter 2.08 in this volume). The response of the atoms inside the medium to the incident EM wave is ...
Here terms of the Vlasov equation are determined from observations of electron phase-space density gradients measured by the four Magnetospheric Multiscale spacecraft in the vicinity of magnetic reconnection at Earth’s magnetopause. We identify which electrons in velocity space substantially support the...
