magnetic

I highly doubt that, they're probably ferromagnetic (ferrous for short), meaning they're attracted to magnets. If they were themselves magnetic, they would get stuck to each other and be hard to use.

I believe ferromagnetic is a subset of magnetic rather than a separate class and that calling iron, for example, magnetic is not incorrect. I believe what you're describing are "permanent magnets".

Here are some usage examples:

e: "Ferrous" refers to iron specifically. Ferromagnetism was named after iron's magnetic property.
