Re: Cenco magnets: remagnetizing

of my contributions to the betterment of mankind is to help a local public
school teacher by strengthening all her Cenco magnets using one of our big
demonstration magnets, I hope in the proper polarity.

I tried this with our CENCO bar magnets but failed miserably. After
several hours in a very large research magnet the bar magnets were
stronger slightly than before but faded very quickly. The next trial
will involve heating the bar magnets and letting them cool in a large
field.
