About Amperes per metre
The ampere per metre (A/m) is the SI coherent unit of magnetic field strength H, expressing the magnetomotive force per unit length. It defines how strongly a field drives magnetic flux through a material. Earth's geomagnetic H field is approximately 40-60 A/m; a typical transformer core operates at 100-1000 A/m. 1 A/m = 1 A m⁻¹.
About Kiloamperes per metre
The kiloampere per metre (kA/m) equals 10³ A/m. The primary practical unit for strong magnetic fields - MRI scanner bore fields of 1-3 T correspond to 800 kA/m-2.4 MA/m in free space; coercivity of hard ferrite permanent magnets (ceramic) is 150-300 kA/m; NdFeB magnets have coercivity 900-2000 kA/m. 1 kA/m = 10³ A/m ≈ 12.566 Oe.
