sähkömagneetti
Sähkömagneetti is the Finnish word for electromagnet. An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of a wire wound into a coil. A current passed through the wire generates a magnetic field. This magnetic field is localized around the coil.
The strength of the magnetic field produced by an electromagnet can be varied by changing the amount
Electromagnets are widely used in various applications. They are found in electric motors, generators, relays, loudspeakers,
