flywheel magnets

Recommended Posts

Odd question;

Do magnets "go bad", get weaker??

Had a customer ask me if there was any way to measure, he thought his were getting weak.

I guess science class was too long ago, I don't remember.

Generally, I would say no to them going bad. Some things that could have an effect on them from what I understand would be abnormal heat (not sure what it would do to a magnetic field, but have been told it can affect it), being exposed to another strong magnetic field, and severe impact (if they are fractured it would mess with the proper magnetic field). Those may or may not be legit reasons, just some things I have heard discussed over the years. Tim

I have heard this statement before and used it as a reference. " Press a 1/4 inch flathead screwdriver against the magnet. Let go of the screwdriver. If the magnet can hold the screwdriver in place then it is OK; if the screwdriver drops then the flywheel magnet is worn out and you will have to replace it."

Magnets slowly lose their strength, we had to check them every 6 months for "gauss" strength. Physical abuse like what was mentioned above can accelerate the decay
