Here are some examples:
* Iron: The most common and well-known example.
* Nickel: Used in many alloys and magnets.
* Cobalt: Used in strong permanent magnets.
* Gadolinium: A rare-earth metal with a very strong magnetic attraction.
* Steel: An alloy of iron, carbon, and often other elements. Steel is often used in magnets because it can be made very strong.
These materials have strong magnetic properties due to the alignment of their electrons. They are often called magnetic materials or magnetic substances.
Important note: Some substances, like paramagnetic materials, are weakly attracted to magnets. However, they are not considered "magnetic" in the same way as ferromagnetic materials.
