This paper employed an electrical circuit simulator to investigate electrodynamic suspension system (EDS) for passenger rail transport applications. Focusing on a null-flux utilizing figure-eight-shaped coils (8-shaped coils), the aim was characterize three primary electromagnetic forces generated in EDS and compare findings with existing literature. The dynamic theory (DCT) approach utilized m...

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...

this paper presents a new method called vespiary regular hexagonal (vrh) model to calculate parasitic capacitance between conductor wire filaments of one turn of a coil and between conductor wires filament and liner and also total capacitance of n-turns having single-layers, multi-conductor wire filaments of the helix magneto cumulative generator (mcg) coil. the presented method is an analytica...

Introduction: One of the major causes of image non-uniformity in MRI is due to the existence of  non-homogeneity in RF receive and transmit. This can be the most effective source of error in  quantitative  studies  in  MRI  imaging.  Part  of  this  non-homogeneity  demonstrates  the  characteristics of RF coil and part of it is due to the interaction of RF field with the material being  imaged...
