Generally, a system for generating a magnetic field having a desired magnetic field strength and/or a desired magnetic field direction is provided. 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).

Systems and methods are disclosed that may be implemented to indicate real time availability of individual key assemblies for user input to an information handling system. In one embodiment, the disclosed systems and methods may be implemented to retract an individual key assembly of a user input device (e.g., such as keyboard matrix, game controller, game pad, computer mouse, etc.) when the key assembly is, or becomes, unavailable for input to a user application (e.g., such as a computer game) that is executing on a host programmable integrated circuit (e.g., such as host CPU) of an information handling system. Such a retracted key assembly may then be extended when it becomes available for input to the user application.
