   Coercive force or Coercitive force (Magnetism), the power
      or force which in iron or steel produces a slowness or
      difficulty in imparting magnetism to it, and also
      interposes an obstacle to the return of a bar to its
      natural state when active magnetism has ceased. It plainly
      depends on the molecular constitution of the metal.
