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.
