摘要：
Electromagnetic navigation systems and methods detect ambient or extraneous magnetic interference by inhibiting the navigation system from generating an electromagnetic field and measuring, with a sensor, the strength of a magnetic field at one or more frequencies of and at one or more phases associated with the electromagnetic field generated by the navigation system. The systems and methods may further determine whether the strength of the magnetic field is greater than a threshold. Based on this determination, an alert or message may be generated.
