Title:
DEVICE, SYSTEM, AND METHOD FOR OBTAINING MAGNETIC MEASUREMENTS WITH PERMANENT MAGNETS
Document Type and Number:
Japanese Patent JP2022095630
Kind Code:
A
Abstract:
To achieve desired magnetic field strength which features sufficient homogeneity and/or stability, and/or reduces the total weight of a magnetic measurement system.SOLUTION: A magnetic field device 200 is provided, comprising a first magnet 201, a first ferromagnetic element 202 located adjacent to the first magnet, a second magnet 221, a second ferromagnetic element 222 located adjacent to the second magnet relative to the first ferromagnetic element to create a gap between the first ferromagnetic element and the second ferromagnetic element, and a third magnet 230 located in the gap between the first ferromagnetic element and the second ferromagnetic element.SELECTED DRAWING: Figure 1B
