Simulation of Axial Components of Magnetic Field of Annular Magnet

In the article the explanation is offered to the effect of change of the direction of magnetic field of the magnet of a ring form magnetized perpendicular to the magnet plane. Subject to development and the focus of this article is the behavior of a component of magnetic field along an axis of a ring magnet. The explanation for change of the sign of tension of magnetic field of a ring permanent magnet at change along ordinate axis combined with its center was for the first time received. It was revealed that with increase in distance along ordinate axis at distance over a surface of the bases of a permanent magnet magnetic field from a magnet with a smaller radius which gradually decreases due to influence of a magnet with a big radius prevails. For carrying out experiments the installation consisting of the device for the measurement of the magnetic field, a ruler for measurement of distances, fixtures and clamps was collected. Modeling of magnetic fields of a ring permanent magnet is also executed. The reliability of the received theoretical results is confirmed by pilot studies. The received results can be used when designing various magnetic systems and in particular the magnetic systems of magnetostriction converters of movement. As ring permanent magnets are used in many devices and sensors, information obtained in article can be used also in other branches.
