strength of magnets- vintage motors

does anyone here have any experience with magneto magnets? I'm wondering if the magnets on older motors, (60's, 70's 80's ) tend to get weaker over time. I repair them and have often wondered if their strength has diminished and thereby affects their ability to generate strong spark through the coils? Pondering the value of looking into buying a gause meter, or magnetisers to revive some of the old flywheels.
Any comments would be appreciated
 
Did I answer this question somewhere on another forum? Anyhoo, flywheel magnets made since WWII simply don't go bad.
