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 However, it has been largely superseded by the ampere per meter in most modern electrical engineering and physics applications.

Ampere per Inch

A/in

Definition

The Ampere per Inch (A/in) is a unit of linear current density equal to approximately 39.37 amperes per meter. It is used in applications where imperial units are preferred, particularly in North American engineering and manufacturing contexts.

History/Origin

The ampere per inch developed as part of the imperial system of units, providing a practical measure for current density in industries and applications that traditionally use imperial measurements. It bridges the gap between metric and imperial systems.

Current Use

Ampere per inch is used in North American electrical engineering, manufacturing, and industrial applications where imperial units are standard. It is particularly common in power distribution, electrical equipment design, and in contexts where inch-based measurements are more practical.
