Kilooersted (kOe)
The kilooersted is 1000 oersteds, about 79.58 kA/m. Magnet grade tables commonly give coercivity in kOe.
Symbol: kOe
Quantity: magnetic field strength (H field) and coercivity
SI relation: 1 kOe = 79577.47154595 A/m (exact)
Derivation: 1 kOe = 1000 Oe = 10⁶/(4π) A/m ≈ 79.577 kA/m
Exact: yes, by definition
Typical uses
- NdFeB and SmCo magnet grades (for example HcJ 12–30 kOe)
- Hard magnetic material data
