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 ...
Materials may be classified magnetically on the basis of their permeabilities. Adiamagneticmaterial has a constant relative permeability slightly less than 1. When a diamagnetic material, such asbismuth, is placed in a magnetic field, the external field is partly expelled, and the magnetic flux dens...
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. ...
