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:

https://www.reddit.com/r/explainlikeimfive/comments/nvim3d/eli5_why_are_iron_cobalt_and_nickel_magnetic_but/

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