What Is This Tool?
This converter transforms values from ampere per inch (A/in), a unit of linear current density, into oersted (Oe), a unit of magnetic field strength used primarily in cgs electromagnetic systems. It helps relate current distributed along a conductor to corresponding magnetizing field strength values.

Specifying current distribution along long conductors such as antenna elements
-
Analyzing thermal and electromagnetic performance of busbars, rail contacts, and PCB traces
-
Converting current densities into magnetizing field strength for cgs-based magnetics literature and datasheets
-
Characterizing magnetizing fields and hysteresis loops in ferromagnetic material studies
-
Applying approximate fields of small permanent magnets or lab electromagnets
Tips & Best Practices
-
Understand that ampere/inch measures linear current density, whereas oersted refers to magnetic field strength
-
Use the conversion to bridge SI and cgs electromagnetic unit systems carefully, considering different physical meanings
-
Apply the tool mainly in contexts involving electromagnetic analysis, magnetics research, or material characterization
-
Double-check conversions when using in sensitive or precise laboratory measurements due to approximation
-
Refer to example calculations to validate your conversion process
Limitations
-
Oersted is not a linear current density unit, so converted values represent different physical quantities
-
Conversion is approximate and context-dependent when relating different electromagnetic unit systems
-
Not suitable for direct substitution without understanding underlying electromagnetic principles
Frequently Asked Questions
-
What does ampere/inch [A/in] measure?
-
Ampere per inch quantifies electric current spread along a length of conductor, representing linear current density.
-
What is the oersted [Oe] unit used for?
-
Oersted is a unit of magnetic field strength commonly used in cgs and older magnetics literature.
-
Why convert ampere/inch to oersted if they measure different quantities?
-
The conversion helps relate current distributions to magnetizing field strength in electromagnetic analyses that bridge SI and cgs systems.
