Beschreibung
Zusammenfassung:	A device includes a housing configured to be implanted in a patient. The device also includes a first magnetic field direction sensor located at a first location within the housing and configured to generate a signal representative of a first direction of a magnetic field at the first location, a second magnetic field direction sensor located at a second location within the housing and configured to generate a signal representative of a second direction of the magnetic field at the second location, and a magnetic field strength sensor configured to generate a signal representative of a strength of the magnetic field. The device further includes a control module configured to identify a source of the magnetic field based on at least one of the signal representative of the strength of the magnetic field and the signals representative of the first and second directions of the magnetic field.
