Understanding Surface Current Density
Surface current density (often denoted as K, Js, or λ) represents the electric current flowing per unit length along a surface or path. It is particularly useful when dealing with current sheets or surface currents.
The SI unit for surface current density is Ampere per meter (A/m).
Note: The Oersted (Oe) is a unit of magnetic field strength (H). Its inclusion here is based on the relationship H = K for an ideal current sheet, where K is the surface current density. 1 A/m ≈ 0.012566 Oe.
| Unit Name | Symbol | Relation to A/m (Approx.) |
|---|---|---|
| Ampere/meter | A/m | Base unit (1 A/m) |
| Kiloampere/meter | kA/m | 1000 A/m |
| Ampere/centimeter | A/cm | 100 A/m |
| Abampere/meter | abA/m | 10 A/m |
| Oersted (magnetic field context) | Oe | 1 Oe ≈ 79.577 A/m |
