{Coercive} 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.
   --Nichol.
         The power of resisting magnetization or
         demagnization is sometimes called coercive force.
