Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
Iron, nickel and some of their alloys are attracted to magnets (only some types of steel). Also, the oppositely charged poles of other magnets or electromagnets.
Many objects have magnets in them. Electric motors and speakers use them. Refrigerator magnets and similar objects use magnets. The magnetron of a microwave oven usually contains two large magnets. Even some types of fake earrings use magnets.
Some magnets are metal. Not all magnets are metal (though I can't offhand think of any magnets that don't at least contain metal), and not all metals are magnets.
the 4 magnetic materials are iron, steel, copper and nickel

Electromagnets
They are permanent, temporary and electromagnets
There are two fundamental types of magnets, permanent and electromagnet. Both of these may be presented in numerous forms, and there seems no merit in considering any particular eleven.
temporary magnets Incorrect, it's electromagnetic.
Yes they do.
