Embodiment Construction

[0034] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the present invention.

[0035] Figure 1AA cutaway perspective view of a magnetic field device 100 according to an exemplary embodiment of the present invention is schematically shown. The magnetic field device 100 may include a housing 111, a first magnet 101 (eg, a first permanent magnet), a first ferromagnetic element 102 (eg, a first pole piece), and a second magnet 121 (eg, a second permanent magnet) and a first A second ferromagnetic element 122 (eg, a second pole piece). In some embodiments, the first magnet 101 and the first ferromagnetic element 102 and / or th...

Abstract

A magnetic field device, with a first magnet, a first ferromagnetic element positioned adjacent to the first magnet, a second magnet, a second ferromagnetic element positioned adjacent to the second magnet and relative to the first ferromagnetic element to create a gap between the first ferromagnetic element and the second ferromagnetic element, and a third magnet positioned between the first ferromagnetic element and the second ferromagnetic element and within the gap.

Description

technical field [0001] In general, the present invention relates to magnetic devices. More specifically, the present invention relates to devices, systems and methods for obtaining magnetic measurements. Background technique [0002] Electromagnetic based instruments can be used to measure the properties of matter and / or to identify its composition. For example, electromagnetic-based instruments capable of performing magnetic resonance wave-spectrum analysis can be used to obtain physical, chemical, and / or structural information about matter (eg, molecules). Typically, in order to perform MRI Bespect analysis, e.g. to provide high-quality measurements (e.g. high-resolution images and / or image contrast) of objects / objects, it may be necessary to The magnetic field is substantially stable and / or uniform. Other applications (eg, Magnetic Resonance Imaging (MRI)) may also require high, stable and / or uniform magnetic field strengths. [0003] Some systems that use a magnetic ...
