I know the older "ALNICO" magnets would lose magnetism unless a piece of ferrous metal was placed across them.
.
I assume the sonicare magnets are not "ALNICO", so this would not necessarily apply.
However, every pack of the small, round, and powerful magnets I have ever purchased came in a stack, and I store them in stacks. They have not seemed to lose any power in years.

I have been pulling off the magnets from our Sonicare toothbrush heads for years and have quite the collection of them. They make excellent uncoupling magnets in my yards as they are quite powerful.
My question is about storing them. Is it better to store them individually or is having them all stuck together in a big ball okay? I wouldn't want to weaken them.
