The study was aimed at designing a system for measuring the distribution of   magnetic field around different magnetic objects including Smart Magnetic Materials. A new type of 3D scanner for monitoring the magnetic field intensity was constructed. The measurement principle is based on internal magnetics properties of materials and the reverse magnetostriction effect (also called the Villari effect). No external magnetizing field is assumed; the entire magnetic effect is due to magnetomechanical principles.

 The new generation of Honeywell magnetosensors were applied to measure filed intensity in 3D. Small size  of measurement area (1.5 mm^3) allows quasi-local measurement of magnetic field.  The aim of this stage of research was to constructed the set for measurement of strength of  very weak magnetic field (10 A/m) around the magnetic objects. In scanner construction  three axis for displacement in directions consistent with sensor axis were applied. It allows measure magnetic field vector in geometrical coordination. Specialized software for data acquisition, processing and visualization of magnetic field vector has been written.

In preliminary parts of work magnetic scanner system allows determination of correspondence between mechanical, electric and magnetic quantities. As a main application for this type of system are: reverse magnetostriction and magnetostriction in smart magnetic materials and composites, martensistic transformation induces plastic strain  in  shape memory alloys, NDT investigation, identification of local plastic deformation and texture of ferromagnetic materials.
