MAGNETIC MODULE

摘要

The invention relates to nanotechnology equipment and, more specifically, to devices that make it possible to observe and measure the properties of objects in a magnetic field. The essence of the invention is that the magnetic module, which comprises a first (outer) magnet with an opening, includes a second (inner) magnet arranged in the opening in the first magnet in such a way that the magnetizations of the magnets point in opposite directions. An embodiment is also possible in which the second magnet is fastened in the opening of the first magnet by means of an adhesive. Embodiments are possible in which a first plate made from a non-magnetic material, or a second plate made from a magnetically soft material, or a third plate made from a magnetically hard material is fastened on the surfaces of the first and second magnets. Embodiments are also possible in which the third plate, made from a magnetically hard material, is magnetized in such a way that the direction of magnetization of said plate is parallel to the magnetization of the first and second magnets, or a fourth plate, made from a magnetically hard material, is magnetized in such a way that the direction of magnetization of said plate is perpendicular to the magnetization of the first and second magnets, or a fifth plate, made from a magnetically hard material, is magnetized in such a way that the direction of magnetization of said plate is at an angle to the magnetization of the first and second magnets. Embodiments exist in which a third (inner) magnet, mounted in the opening in the first magnet, has a thickness that is less than the thickness of the first magnet, or a fourth (inner) magnet, mounted in the opening in the first magnet, has a thickness that is greater than the thickness of the first magnet. Embodiments also exist in which the third (inner) magnet is mounted in the first magnet such that it can move axially in relation to the first magnet, or the fourth (inner) magnet is mounted in the first magnet such that it can move axially in relation to the first magnet. Embodiments are possible in which a first solenoid is disposed around the diameter of the first magnet, or a second solenoid is disposed parallel to the plane of the first magnet, or a third solenoid is disposed between the first and fifth (inner) magnets mounted in the opening in the first magnet. Embodiments are also possible in which a sixth (inner) magnet and likewise the opening in a seventh (outer) magnet are in the shape of a truncated cone, or an eighth (inner) magnet and likewise the opening in a ninth (outer) magnet are in a shape different from cylindrical. All of the above-mentioned technical effects increase the functionality of the device.
