Abstract: A magnetic device may include a magnetic structure, a device structure, and an associated circuit. The magnetic structure may include a patterned layer of material having a predetermined magnetic property. The patterned layer may be configured to, e.g., provide a magnetic field, sense a magnetic field, channel or concentrate magnetic flux, shield a component from a magnetic field, or provide magnetically actuated motion, etc. The device structure may be another structure of the device that is physically connected to or arranged relative to the magnetic structure to, e.g., structurally support, enable operation of, or otherwise incorporate the magnetic structure into the magnetic device, etc. The associated circuit may be electrically connected to the magnetic structure to receive, provide, condition or process of signals of the magnetic device.
