Syn: Strength; vigor; might; energy; stress; vehemence;
violence; compulsion; coaction; constraint; coercion.

Usage: {Force}, {Strength}. Strength looks rather to power as
an inward capability or energy. Thus we speak of the
strength of timber, bodily strength, mental strength,
strength of emotion, etc. Force, on the other hand,
looks more to the outward; as, the force of
gravitation, force of circumstances, force of habit,
etc. We do, indeed, speak of strength of will and
force of will; but even here the former may lean
toward the internal tenacity of purpose, and the
latter toward the outward expression of it in action.
But, though the two words do in a few cases touch thus
closely on each other, there is, on the whole, a
marked distinction in our use of force and strength.

{Coercive force} or {Coercitive force} (Magnetism), the power

depends on the molecular constitution of the metal.
--Nichol.

The power of resisting magnetization or
demagnization is sometimes called coercive force.
