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 Megaoersteds
The megaoersted (MOe) equals 10⁹/(4π) A/m ≈ 7.958 × 10⁷ A/m. Encountered in ultra-high-field pulsed magnet research - National High Magnetic Field Laboratory (NHMFL) 100 T pulsed fields correspond to ≈1 MOe; internal crystalline fields at magnetic rare-earth sites in hyperfine studies are of this order. 1 MOe = 10⁹/(4π) A/m.
