The Wendelstein 7-X is a thermonuclear fusion experiment being built at the Greifswald Branch Institute of the Max-Planck-Institut für Plasmaphysik (IPP). The eddy current distribution is investigated during a transient process in the superconducting coils of the magnet system. Application of volume-grid methods (e.g. FEM) for calculations of the eddy currents in the magnet system is difficult ...

Transportation and refining of heavy metal-bearing oil are associated with the problems localized destruction metal structures elements due to corrosion. In process equipment operation, it was revealed that premature failure steel coils heating tube furnaces at refineries petrochemical plants insufficient strength corrosion resistance steelwork. The study effect structure phase composition 15KH...

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...

background : effects of electromagnetic fields on healing have been investigated for centuries. substantial data indicates that exposure to electromagnetic field can lead to enhanced healing in both soft and hard tissues. helmholtz coil is a device that generates pulsed electromagnetic fields. objective : in this study, a pair of helmholtz coils for enhancing the healing process in periodontiti...

In recent years, the popularity of wireless inductive power transfer (WIPT) system for electric vehicle battery charging (EVBC) is always ever-increasing. In the WIPT inductively coupled coil structure is the heart of the system and the mutual inductance (MI) between the coupled coils is the key factor for effective power transfer. This paper presents the analysis of mutual inductance between t...

ICCS conductors behave anomalously. Several anomalies have been documented: quenches driven by pulsig fields (referred to as ramp-rate limtations), and energy margins that show a transition between a "well-cooled" and an "ill-cooled" regime (marking a transition between high energy margin at low transport current and low energy margin at higher currents). In this paper, a novel model will be de...

Standard Pulsed Eddy Current Systems, as RTD-INCOTEST© equipment, use receiver coils to measure eddy current decay in conducting objects. Advantages of full coils, as sensor for the eddy current, are its simple construction and the possibility of eddy current focussing. But, some disadvantages are the high induction voltage due to a large pulsed signal, the large sensor area and the low coil’s ...
