Calculating Distributions of Pulsed Magnetic Fields under Hysteretic Interference

Resumo

Calculations are presented for the distributions of electric voltage readings U(x) from a magnetic field transducer that correspond to the distributions of residual magnetic fields that emerge in a magnetic carrier acted upon by pulsed magnetic fields of different polarity from a linear inductor. The graphs have been produced using Delphi programming language. The phenomenon of magnetic field hysteretic interference (HI) in a magnetic carrier with hysteresis loops described by the dependences in the form of an arctangent has been used to inspect objects made of electroconductive materials, thus improving the accuracy of inspection by several times.
