Magnetic Field Polarity, Including Definitions and Determination of Polarity

PURPOSE
The purpose of this standard is to eliminate confusion, by
providing definitive statements of the conventions involved in
determining the polarity of a magnetic field, and by describing
basic practical methods that may be used, with necessary
precautions. While it might be considered that the conventions are
basic text-book material, it is found that few text-books state
them explicitly, and disagreement among engineers is observed as a
result. Since some electrical or electronic devices may be
destroyed, if the magnetic field polarity is incorrectly
determined, it is important that disagreement or confusion be
avoided.
