Abstract
There is disclosed a technique for measuring the magnetic field of a sample, such as sheet material having one or more magnetic poles, including effecting relative movement between a magnetically responsive transducer and the sample to scan the magnetic field while controlling the distance between the transducer and sample. Apparatus is provided to practice such technique, including control of the relative scanning movement, and of the transducer/sample spacing. A breakaway support for the transducer prevents damage in case an obstruction is struck, and a circuit operates on the analog signal produced by the transducer to provide useful output information representative of the magnetic field.
