The prototype of a magnetic locator based on a magnetoresistive compass is designed and studied. The effectiveness of the modified algorithm and software for calculating spatial and angular coordinates of a magnetic dipole and the electronic part of a prototype magnetic capsule is shown. Software for data processing and 3D visualization of the trajectory of magnetic dipole motion is developed. It is shown the software can be used in a computer-aided design system (CADS).

Results are presented from research on developing a theory and model of magnetic location based on a set of manufactured magnetoresistive compasses. The working capacity of the developed algorithms and software for calculating the spatial and angular coordinates of a magnetic dipole, the electronic part of the magnetic location model, and the software for processing and visualizing data are described.

We show the results of our studies related to control over objects by the magnetic field they generate. We propose a model to compute the current and its magnetic field in a conductor with a rectangular defect. We describe the developed and produced anisotropic magnetoresistive gradiometer head to measure surface magnetic fields in order to control the functionality of electronic components by the magnetic field they generate. We describe the operation of a testbed with a test circuit in the plotter.
