What’s the difference between hard and soft magnetic materials?
These distinctions refer specifically to ferromagnetic and ferrimagnetic materials, not just hard and soft materials. There are super-soft, very-soft, soft, semi-hard, and hard magnetic material classifications based on the magnetic coercivity (HC) measured in ampere/meter (A/m) units or Oersteds (Oe). This FAQ is focused primarily on soft, semi-hard, and hard magnetic materials. It begins with […]
