Physics Explanation
Domain Parameters:
- Domain size: 1µm cube (10⁻⁶ m)
- Iron density: 7.9 g/cm³
- Molecular mass: 55 g/mole
- Atomic dipole moment: 9.27 × 10⁻²⁴ A m²
Calculations:
Volume = (10⁻⁶ m)³ = 10⁻¹⁸ m³
Mass = 7.9 g/cm³ × 10⁻¹² cm³ = 7.9 × 10⁻¹² g
Atoms = (7.9 × 10⁻¹² × 6.023 × 10²³) / 55 = 8.65 × 10¹⁰
Max dipole moment = 8.65 × 10¹⁰ × 9.27 × 10⁻²⁴ = 8.0 × 10⁻¹³ A m²
Max magnetization = 8.0 × 10⁻¹³ / 10⁻¹⁸ = 8.0 × 10⁵ A m⁻¹
