* Ferromagnetic materials: These are materials that are strongly attracted to magnets. They include:

* Iron (Fe)

* Nickel (Ni)

* Cobalt (Co)

* Some alloys containing these elements, like steel

* Other materials: Most other materials are not strongly attracted to magnets. These include:

* Non-magnetic metals: Aluminum, copper, gold, silver, etc.

* Plastics

* Wood

* Glass

* Water

* Most other substances

A few additional points:

* Paramagnetic materials: These are weakly attracted to magnets, but not strongly enough to stick. Examples include aluminum and platinum.

* Diamagnetic materials: These are weakly repelled by magnets. Examples include water and copper.

* The strength of the magnet matters: A very strong magnet might be able to weakly attract some paramagnetic materials.

* The shape and size of the magnet matters: A thin, flat magnet may not be strong enough to stick to a large piece of metal.
