Oersted

Definition

The Oersted (Oe) is a CGS unit of magnetic field strength that is equivalent to approximately 79.58 amperes per meter in terms of linear current density. It was originally defined as the magnetic field strength produced by one abampere per centimeter of current.

History/Origin

Named after Hans Christian Ørsted, a Danish physicist who discovered the relationship between electricity and magnetism, the oersted was a fundamental unit in the CGS electromagnetic system. It was widely used in magnetic field measurements before the adoption of the SI system.

Current Use

The oersted is still used in some specialized applications, particularly in magnetic materials research and in contexts where CGS units are preferred. However, it has been largely superseded by the ampere per meter in most modern electrical engineering and physics applications.

Abampere per Inch

abA/in

Definition

The Abampere per Inch (abA/in) is a CGS electromagnetic unit of linear current density equal to approximately 393.7 amperes per meter. It combines CGS electromagnetic units with imperial length measurements, representing a hybrid approach to current density measurement.

History/Origin

The abampere per inch emerged as a practical unit in contexts where CGS electromagnetic units were used but imperial length measurements were preferred. It was particularly relevant in North American scientific and engineering applications during the transition period between unit systems.

Current Use

The abampere per inch is largely historical and rarely used in modern applications. Its relevance is confined to historical scientific literature and academic discussions that explore the various systems of units used in electromagnetism before the widespread adoption of the SI system.
