• Analysis of the influence of ferromagnetic contaminations in plastics on the measurements of disturbances of magnetic field of the Earth

  Publikacja

  • M. Wołoszyn
  • K. Jakubiuk
  • M. Flis

  - Przegląd Elektrotechniczny - Rok 2016

  Plastics can be contaminated with small particles or filings with ferromagnetic properties. These contaminations cause significant disturbances in the magnetic field in the case of taking measurements of very low magnetic fields. The analysis of the influence of contaminated plastics on magnetic measurements is presented in this paper.

• Isolation of the relative decrease in magnetic permeability contribution to reluctance of an open magnetic circuit based on stray field measurements

  Publikacja

  • Z. Usarek

  - NDTnet - Rok 2018

  The goal of the study was to evaluate a relative decrease in magnetic permeability in open magnetic circuits based on stray magnetic field measurements. The boundary element method was used to simulate magnetic circuits with variable geometry and variable magnetic permeability. The simulated magnetic circuits were rectangular or bone-shaped flat samples. Reluctance was increased in the middle of the samples resulting in leakage...

  - Rok 2007

  The 3-axis fluxgate magnetometer requires conducting a precise calibration in the magnetic field whose value is determined and which is characterized by the high uniformity of the distribution of the field, especially along the axis of the sensors. The generation of the magnetostatic field characterized by the high uniformity, can be achieved by using the Helmholtz's coils. The requirements of the uniformity of distribution of...

• Multidipoles model of ship's magnetic field

  Publikacja

  • K. Jakubiuk
  • P. Zimny
  • M. Wołoszyn

  - Rok 2011

  Ships made of ferromagnetic metals interfere with Earth's magnetic field in their surrounding. The disturbance of the magnetic field makes possible localization and even identification of the ship, which could determine a threat to the ship. The measurement of the magnetic field around the ship enables to determine its magnetic signature. The paper presents a multidipoles model of the ship magnetic field, which allows to determine...

  Do wymuszenia przerzutu prądu z bezpiecznika krótkotopikowego o dużym prądzie znamionowym, lecz małej zdolności wyłączania do do innego - o małym prądzie znamionowym, lecz dużej zdolności wyłączania konieczne jest wytworzenie przez bezpiecznik krótkotopikowy wysokiego napięcia łukowego. Do tego celu bezpiecznik z topikiem o długości 1 mm wyposażono w rożki łukowe i płykową komorę dejonizacyjną oraz zastosowano zewnętrzne pole...

• Research of leakage magnetic field in deenergized transformer

  Publikacja

  • J. Horiszny

  - COMPEL-THE INTERNATIONAL JOURNAL FOR COMPUTATION AND MATHEMATICS IN ELECTRICAL AND ELECTRONIC ENGINEERING - Rok 2018

  The article deals with the issue of the numerical analysis of the magnetic field occurring around the transformer after it has been powered down. The main goal of this analysis was to examine if it is possible to identify the residual fluxes in the transformer legs based on this fields’ measurements. It was also intended to determine the type and the location of magnetic sensors. Numerical analysis of the magnetic field was performed....

• Performance of lubricated sliding contact in magnetic field

  Publikacja

  • T. Stolarski
  • Y. Makida

  - TRIBOLOGY LETTERS - Rok 2012

  Results of experimental studies concerning theinfluence of permanent magnetic field on wear of lubricatedsliding contact operating at short stroke and highfrequency are presented. It was found that horizontalmagnetic is affecting performance of the contact. Thejagged delamination regions produced in the presence of amagnetic field can be regarded as easily undergoing oxidisationbecause oxygen is readily adsorbed there. Magneticfield...
