Self-inductance coefficient for toroidal thin conductors
We consider the inductance coefficient for a thin toroidal inductor whose thickness depends on a small parameter ε > 0. An explicit form of the singular part of the corresponding potential u is given. This allows to construct the limit potential u (as ε → 0) and an approximation of the inductance coefficient L. We establish some estimates of the deviation u − u and of the error of approximation...
متن کاملComputational Study of Electromagnetic Fields, Eddy Currents and Induction Heating in Thin and Thick Workpieces
A set of 2D steady state finite element numerical simulations of electromagnetic fields, eddy currents distribution and induction heating pattern has been done for different thicknesses of ametal workpiece. Comparison between the calculation results show the importance of workpiece thickness on induction heating process including electromagnetic field distribution, eddy currents pattern, heatin...
متن کاملA Fortran 77 computer code for damped least-squares inversion of Slingram electromagnetic anomalies over thin tabular conductors
A FORTRAN 77 computer code is presented that permits the inversion of Slingram electromagnetic anomalies to an optimal conductor model. Damped least-squares inversion algorithm is used to estimate the anomalous body parameters, e.g. depth, dip and surface projection point of the target. Iteration progress is controlled by maximum relative error value and iteration continued until a tolerance va...
متن کاملElectromagnetic Induction Studies
This report constitutes an attempt to review the major developments and identify important trends in the broad field of geophysical electromagnetic nduction and related phenomena over the past four years. Following in the spirit of previous reports of this type [e.g., Filloux, 1979; Hermance, 1983b], the work of US researchers will be emphasized, although we will cover foreign research when app...
متن کاملElectromagnetic Induction ( Paper Ii )
Typical components of a metal detector include a transmitter and receiver coil. As depicted in Figure B.1, electric currents that flow in the transmitter coil radiate a primary magnetic field that penetrates the surrounding medium and any nearby metallic object. A timechanging primary magnetic field will induce so-called eddy currents in the buried object, and these currents in turn radiate a s...
