pysyvämagneetti
Pysyvämagneetti refers to a permanent magnet in Finnish. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. Unlike electromagnets, permanent magnets do not require an external electric current to maintain their magnetism. The magnetic field is produced by the alignment of microscopic magnetic domains within the material. These domains are regions where the magnetic moments of atoms are aligned in the same direction.
Permanent magnets are typically made from ferromagnetic materials such as iron, nickel, cobalt, and their alloys.
The applications of permanent magnets are widespread. They are found in electric motors, generators, loudspeakers, magnetic
