Linear Current Density Units Explained

Ampere/meter (A/m)

The SI unit of linear current density, representing the amount of electric current per unit length. 1 A/m = 0.01 A/cm.

Common uses: Electromagnetic field calculations, wire and conductor analysis, solenoid design.

Ampere/centimeter (A/cm)

Linear current density in the CGS system. 1 A/cm = 100 A/m. Often used in laboratory and practical applications.

Common uses: Coil and solenoid winding specifications, practical engineering applications.

Ampere/inch (A/in)

Linear current density in the imperial system. 1 A/in ≈ 39.37 A/m. Used primarily in North American industrial applications.

Common uses: Wire specifications, conductor sizing in imperial measurements.

Abampere/meter (abA/m)

A CGS electromagnetic unit of linear current density. 1 abA/m = 10 A/m. Part of the CGS-emu system.

Application: Legacy scientific and electromagnetic calculations in CGS systems.

Oersted (Oe)

A CGS unit of magnetic field strength, related to linear current density. 1 Oe ≈ 79.58 A/m. Historically important in magnetism.

Historical use: Magnetic field measurements in CGS systems; largely replaced by Tesla in SI.

Gilbert/centimeter (Gi/cm)

A CGS unit expressing magnetomotive force per unit length. Equivalent to oersted in certain applications. 1 Gi/cm ≈ 0.795 A.

Application: Transformer and inductor design in CGS-based calculations.

Linear Current Density Context

  • Typical solenoid: 100-500 A/m for laboratory setups
  • Strong electromagnet: 1000-10000 A/m or higher
  • Wire winding: Current density depends on wire gauge and insulation
  • High-field magnet: Can exceed 100,000 A/m in specialized applications
  • Magnetic field strength: Related to magnetomotive force (MMF) per unit length
