A method for magnetic control of articles made of ferromagnetic material according to which before control material is magnetized. By the signals from the field sensors placed over the controlled surface, vector function of field strength distribution is determined. Through the set of characteristics of the vector function informative parameters are calculated, with following determination of location, parameters and the type of the defect. Scanning surface of the article with complicated form is performed through electronic interrogation of field sensors fixed as an immovable with respect to the article matrix on flexible non-ferromagnetic material able to fit the controlled surface with complicated shape. At that each sensor registers information by the components by three directions X, Y and Z. |
