When there are moving electrons, there is a magnetic field. No moving electrons = no magnetic field.
We can make an electromagnet by passing an electric current (= moving electrons) through a wire coil. And that field may be strengthened further by placing a soft iron core inside the coil.
There are also permanent magnets, with which you're already familiar - a compass, a fridge magnet and so on. These are materials in which the electrons have aligned themselves so their spins are parallel. (More moving electrons - even if they are just spinning).
The commonest members of this group are iron and nickel materials, though a dozen or so materials may aid the strength of the magnet.
Electromagnetic machines are such things as electric generators and motors, relays and solenoids.
The Earth has a magnetic field, generated we believe by electric currents flowing in the mantle, roughly parallel to the Equator.
Industrial ceramic magnets otherwise known as large rotating drum magnets, are used by the metal scrap and recycling industries. The magnets are used to separate and process metals. If you are looking to recycle one of these magnets you can find a company that uses them for recycling.
There are 216 magnetic spheres that make up the Neocube, BuckyBall, Or Zen Magnets.

they bend and/or focus the beam.
Refrigerator magnets, car magnets, neodymium magnets are names of small magnets.
put magnets and put magnets on a car and put magnets on a car and put the car on the road and put the magnets on the road and put the magnets touch the magnets on the road and on the car
since magnets are all ready magnetised when found in nature called natural magnet artificial magnets that are made by man are called artificial magnets
which is the cheapest magnets
bigger magnets. 'cus bigger magnets have more force(also so called as attraction) . thus, smaller magnets have less attraction.
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.
Two household objects that have magnets are: fridge magnets, and sizzlers
Some of them do have magnets. Childrens alphabet magnets are an example.
permanent magnets
because it is bigger than the little magnets and has more power than the little magnets do.
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 do not quote me on that.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.
Nothing. Magnets are not alive.
