Magnets
Magnets are made out of a material called alloys. ... Magnets always have south and north poles. ... Magnets have lots of miniature magnetized areas which are called magnetic domains. ... There are two types of magnets, temporary magnets and permanent magnets. Permanent magnets are magnetized for a long period of time and always work. Temporary magnets are only magnetized for a short period of time and only work while they are connected to another magnet.
