Abstract
A method and system for sensing magnetic fields using an AC current carrying wire which vibrates or moves in the presence of a magnetic field. The system uses the wire movement to determine one or more characteristics of the field. The wire is connected at a first and second location to the base with an portion between the connection locations having an apex spaced apart from the base. The monitoring system detects movement of the wire at the portion while an electrical current having the same frequency as the mechanical resonant frequency of the wire is sent through the wire and a magnetic field surrounds the portion. The reporting system determines one or more characteristics of the magnetic field based upon the detected movements.
Claims22
A system for sensing fields, the system comprising:
- a conductive element connected at a first and a second location to a base, a portion of the conductive element between the first and second locations has a section in the portion which forms an apex with respect to one or more other sections within the portion and the portion is spaced apart from the base;
- a monitoring system that detects movement at least at the section in the portion which forms the apex while an electrical current is sent through the conductive element and a magnetic field surrounds at least the portion;
- and
- a reporting system that determines one or more characteristics of the magnetic field based upon the detected movement of the section in the portion of the conductive element.
A method for sensing fields, the method comprising:
