                                                  Warburton.

   {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.
