Mathematical modeling of nonstationary electromagnetic fields of a defectoscope of casings. (Russian. English summary) Zbl 1024.86003
Summary: This work is devoted to modeling of nonstationary electromagnetic fields arising in defectoscopy of oil-and-gas casings. Modeling is carried out in terms of the vector potential in the axisymmetric case. A method is proposed for taking account of discontinuity of the electromagnetic field on the boundary of various materials.
