Studies were made of the influence of the permeability of a magnetic conductor made of cast iron (3.2% carbon) and steel (0.2% carbon) on the efficiency of strong-field electromagnets. The permeability was modified within the range 1000-5000 via thermal treatment of the metal in the ...
electrical conductivity and magnetic permeability of conductor as well as the testing frequency.This paper produces the mathematics model to describe the relationship among those factors.The model is expected to provide a reliable criteria for measuring the TDP of eddy current inside solid conductor. ...

A thin uniformly magnetized disk lies between a semi‐infinite conductor and a half‐space filled with magnetic material of finite permeability (keeper). Maxwell's equations are solved and an expression given for the magnetic field at the center of the disk when the magnetization is an arbitrary...
intrinsic permeabilityargillaceous rockAn analytic theory is developed for the diagonal conductivity $\\sigma_{xx}$of a 2D conductor which takes account of the localized states in the broadenLandau levels. In the low-field region $\\sigma_{xx}$ display the Shubnikov-deHaas oscillations which in...

This paper quantitatively accounts the electromagnetisms of the proposed sensor from sensing property, flux distributions and eddy-current loss in each part of the sensor body. Moreover, material characteristics for the proposed shield, such as relative permeability and conductivity, are found. 展开 ...
The read-write conductor means is positioned between the two legs and is thereby inductively coupled to the core. The higher permeability layer is narrow in a direction perpendicular to both the length of the leg and the thickness of the layer, is adjacent the conductor means and is saturated...
