Abstract:
A magnet scanning device uses a helical scanning technique to scan a cylindrical magnet along a helical path on a cylindrical surface that corresponds to the cylindrical magnet. Based on the magnetic field profile, the device may detect any unacceptable irregularities in the magnetic field and identify a location of the cylindrical magnet associated with the irregularity.
