supermagnete is a kind of material which can produce a magnetic field,this field sightless and intangible,howerver,it's a significant character of a magnet, a strong power that can pull on other metals, such as irons,other magnets. A permanent magnet is an object which is made from a kind of material that has its own persistent magnetic field. for instance, a fridge magnet is stuck on a fridge door to hold notes, there  are two kinds of magnets, one is soft magnets whose magnetism can't last for long time. another one is hard magnets whose magnetism can last for much longer time. and also, its magnetism is very strong.
    Magnets are used for many areas:
   1) magnetic recorder: Video Home System tapes contain a reel of magnetic tape, in computers, floppy diskds and hard disks record data on a thin magnetic coating.
   2) loud speakers and microphone: most speakers contain a permanent magnet and a current carrying coil, the coil is wrapped around a reel attached to the speaker cone and carries the signal as changing current that interacts with the field of the permanent magnet.
   3) fridge magnets: which are used to decorate kitchens, as a gift or souvenir or to hold a note or picture to the fridge door.
