A good question. Iron, cobalt and nickel are all ferromagnetic(strongly magnetic) elements. In addition, some metals which are not magnetic when pure make very strong magnets when alloyed with other non-magnetic metals. And just recently magnetic plastics have been made. A few compounds are magnetic; lodestone, or magnetite is an oxide of iron with the chemical formula Fe2O3. It's a naturally-occurring mineral and the Chinese discovered that it's magnetic and the used it, centuries ago, to make the first compasses.

Magnets affect anything with iron in it. Most notably iron and steel products, but the degree of effect is determined by the strength of the magnet, distance from the object in question and amount of iron in the object. Some stainless steels have iron in them but are not affected by magnets. Navy ships are demagnetized by a process called degaussing which greatly reduces their magnetic field so that certain mines and torpedoes are not activated by the ship's passing. Certain biological processes are affected by magnetism because iron is an element in the body. Migrating birds are believed to have a sensory compass that allows them to return to the same nesting and breeding grounds year after year.

Strictly speaking, virtually all normal matter (except neutrons, which have no charge) can be at least marginally affected by a magnetic field. (This is why MRI--magnetic resonance imaging--works.) But in terms of the commonly observed phenomenon of magnetism, yes, iron or a related metal must be in the mix.

Everything is to some degree affected by magnets, even people. Iron and steel have the strongest attraction to magnets.

A few other metals (nickel and cobalt) are ferromagnetic, but iron is the most.

no they work with other metals too but they do not work with some, iron is just the most common

why don't you go put a magnet on someting that's not iron and find out.

any ferrous metal
so yeah... iron and anything thats an alloy with iron
