Coercimetry with Magnetization by a U-Shaped Electromagnet

Autor: A. V. Mikhailov, S. V. Zhakov, Yu. L. Gobov, Yu. Ya. Reutov

Publikováno v: Russian Journal of Nondestructive Testing. 55:935-941

A method is proposed for measuring the coercive force using a U-shaped electromagnet with a gap between the electromagnet poles and the test sample. It is demonstrated that the device can operate in a dynamic mode under pulsed magnetization reversal.

Solving the Inverse Geometric Problem of Magnetostatics for Corrosion Defects with Allowance for Nonlinear Properties of Ferromagnet

Autor: S. E. Popov, A. V. Nikitin, Yu. L. Gobov

Publikováno v: Russian Journal of Nondestructive Testing. 54:849-854

A method is proposed for solving the inverse problem of magnetostatics with allowance for a nonlinear dependence of the relative magnetic permeability of a ferromagnet on the applied external field. The method has been investigated for metal loss def

Magnetic Method for Nondestructive Testing of Rebar in Concrete

Autor: Ya. G. Smorodinskii, Yu. L. Gobov, A. V. Mikhailov

Publikováno v: Russian Journal of Nondestructive Testing. 54:871-876

It has been shown theoretically and experimentally that locally magnetizing rebar through a protective layer of concrete makes it possible to determine both the depth of the protective layer of concrete and the diameter of rebar based on stray magnet

Solving the Inverse Geometric Problem of Magnetostatics for Corrosion Defects

Autor: A. V. Nikitin, S. E. Popov, Yu. L. Gobov

Publikováno v: Russian Journal of Nondestructive Testing. 54:726-732

A method is proposed for solving the inverse problem of magnetostatics. The method has been investigated for metal-loss defects located on the side of a ferromagnetic plate opposite to magnetic transducers, without imposing any conditions on defect s

Measuring coercive force in local domains of a sample

Autor: S. V. Zhakov, A. V. Mikhailov, Yu. L. Gobov

Publikováno v: Russian Journal of Nondestructive Testing. 53:779-784

A method has been proposed for determining the coercive force in local domains of bulk samples magnetized normally to the surface. The method is based on local measurement of the normal magnetic-field component at the sample surface, in the gap betwe
