摘要： Embodiments of the present disclosure relate to methods and systems for switching a magnetic field external to a magnet assembly having two permanent magnets, including a fixed permanent magnet portion and a switching permanent magnet portion, where a switching magnetic field is used to switch the magnetization of the switching permanent magnet portion, but not switch the magnetization of the fixed permanent magnet portion. In this way, the fixed permanent magnet portion has a fixed magnetization, such that the direction of magnetization of the fixed permanent magnet portion remains the same during switching of the magnetization of the switching permanent magnet portion, and the switching permanent magnet portion has a switching magnetization, such that the direction of magnetization of the switching permanent magnet portion is switched during switching of the magnetization of the switching permanent magnet portion.

摘要： Embodiments of a magnetic field sensor of the present disclosure includes magnetoelectric nanowires suspended above a substrate across electrodes without substrate clamping. This results in enhanced magnetoelectric coupling by reducing substrate clamping when compared to layered thin-film architectures. Accordingly, the magnetoelectric nanowires of the magnetic field sensor generate a voltage response in the presence of a magnetic field.

摘要： Provided herein is a magnetic apparatus for collecting superparamagnetic particles from a subject. The superparamagnetic particles are previously injected into the subject and have ligands bound thereto that are specific for one or more non-cell biomarkers. In one embodiment, the superparamagnetic particles are injected into and retrieved from a cavity such as a joint cavity. These compositions and methods allow for the sequestration and removal of inflammatory mediators, as both a diagnostic of the local immune response and a therapeutic that can reduce inflammation in the local disease environment.

摘要： Embodiments of the subject invention relate to an electropermanent magnet core (EPM core) having two permanent magnets (or two permanent magnet portions where each portion can have one or more permanent magnets), including a fixed permanent magnet portion and a switching permanent magnet portion, where a switching magnetic field is used to switch the magnetization of the switching permanent magnet portion, but not switch the magnetization of the fixed permanent magnet portion. In this way, the fixed permanent magnet portion has a fixed magnetization, such that the direction of magnetization of the fixed permanent magnet portion remains the same during switching of the magnetization of the switching permanent magnet portion, given the magnitude and duration of the switching magnetic field used to switch the magnetization of the switching permanent magnet portion, and the switching permanent magnet portion has a switching magnetization, such that the direction of magnetization of the switching permanent magnet portion is switched during switching of the magnetization of the switching permanent magnet portion, given the magnitude and duration of the switching magnetic field used to switch the magnetization of the switching permanent magnet portion.

摘要： Disclosed are various embodiments for a system configured to characterize a magnetic response of a sample. The system can comprise an electrical source configured to generate a time-varying current supply, an excitation coil system coupled to the electrical source to generate a time-vary magnetic field for application to a sample, and a sensing coil system that senses a magnetic response of the sample in response to the time-varying magnetic field. The sensing coil system can comprise a pick-up coil and a balancing coil that can be translated or rotated. The balancing coil configured to cancel a feed-through induction signal. In another embodiment, the sensing coil system can comprise an adjustable fine-tuning coil that is configured to modify an effect of the cancellation of the feed-through induction signal.

摘要： The present disclosure is directed towards wireless power transfer using one or more rotating magnets in a receiver. An exemplary embodiment provides for a system comprising a transmitter that generates a dynamic magnetic field and a receiver comprising a magnet and a coil. In operation, the magnet rotates in response to the dynamic magnetic field and induces a voltage across the coil.
