A model of a surface flaw of finite length under normal magnetization and calculation of the topography of its magnetostatic field
Source abstract
Abstract
A calculated model of the magnetic field of a surface flaw with a rectangular cross section and a finite length under normal magnetization of the tested surface is proposed. Practically convenient expressions for calculating the phase angle ϕ between the imaginary and real magnetic components have been obtained. An algorithm for estimating the parameters of the flaw and principles of building devices for electromagnetic flaw detection and flaw measurement are proposed.
