The system can include a plurality of magnetic segments and/or a plurality of ferromagnetic segments. Each magnetic segment can be positioned adjacent to at least one of the plurality of magnetic segments. Each ferromagnetic segment can be positioned adjacent to at least one of the plurality of magnetic segments. In various embodiments, a size, shape, positioning and/or number of magnetic segments and/or ferromagnetic segments in the system, as well as a magnetization direction of the magnetic segments can be predetermined based on, for example, predetermined parameters of the system (e.g., a desired magnetic field strength, direction and/or uniformity of the magnetic field, a desired elimination of a magnetic fringe field and/or total weight of the system) and/or based on a desired application of the system (e.g., performing a magnetic resonance imaging of at least a portion of a patient and/or performing a magnetic resonance spectroscopy of a sample).

摘要： A power generation device includes a first magnet member, a second magnet member which is disposed such that the N pole side thereof is in the opposite direction to the N pole side of the first magnet member, a yoke which is disposed between the first magnet member and the second magnet member, an induction coil which is disposed at an outer periphery of the yoke. When the first magnet member and the second magnet member slidingly move in synchronization or when the yoke slidingly moves, the direction of a magnetic flux flowing in the yoke changes to generate an electromotive force in the induction coil.

摘要： A permanent magnet power generating device comprises a first soft magnetic body (1), a coil (2) and a permanent magnet (3). The first soft magnetic body has a first branch (11), a second branch (12), and a third branch (13) arranged at intervals. The second branch is located between the first branch and the third branch. The coil is wound around the second branch. The permanent magnet, which is in the form of “C” shape, is provided with two branches inserted between the first branch and the second branch, and between the second branch and the third branch, respectively. Both of the branches of the permanent magnet are in contact with the first branch and the second branch of the first soft magnetic body, or with the second branch and the third branch of the first soft magnetic body, selectively. The permanent magnet power generating device is low-cost, simple-structure, non-polluting, and suitable for the application of collecting micro energy.
