* Iron: The most common and strongest ferromagnetic material.
* Nickel: Less strong than iron, but still significantly attracted to magnets.
* Cobalt: Similar to nickel in its magnetic properties.
* Gadolinium: A rare earth metal with strong magnetic properties.
Other materials that are attracted to magnets but to a lesser extent include:
* Steel: An alloy of iron with other elements, often containing carbon. Steel is also ferromagnetic but usually weaker than pure iron.
* Some alloys: Certain alloys containing iron, nickel, or cobalt can be magnetic.
Materials that are *not* attracted to magnets include:
* Aluminum: Non-magnetic
* Copper: Non-magnetic
* Gold: Non-magnetic
* Silver: Non-magnetic
* Wood: Non-magnetic
* Plastic: Non-magnetic
It's important to note that even though certain materials are not attracted to magnets, they can still be influenced by a magnetic field. For example, a magnetic field can cause eddy currents in a copper wire, which can create resistance to the magnetic field.
