Coercive power can only influence us to outward
practice. --Bp.
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.
--S. Thompson.
