Ein Körper, der in seiner Umgebung ein M.feld erzeugt, z.B. Eisen, Cobalt, Nickel u. einige andere Stoffe, die sog. Ferromagnetika. Jeder M. hat 2 Pole, Nord- u. Südpol, u. stellt sich bei freier Beweglichkeit in Nord-Süd-Richtung ein. M.e haben meist Stab-, Hufeisen- oder Topfform. Elektromagnet, Magnetismus.
ETYM Latin magneticus: cf. French magnétique.
1. Capable of being magnetized.
2. Determined by earth's magnetic fields.
3. Having the properties of a magnet; i.e. of attracting iron or steel; SYN. magnetized.
4. Of or relating to or caused by magnetism.
ETYM Greek solen channel + -oid.
An electromagnetic device that converts electrical energy to mechanical movement, typically consisting of an electromagnet with a movable rod through the center.
Cylindrical wire coil acting as a magnet when charged.
A coil of wire around an iron core; becomes a magnet when current passes through the coil.
Coil of wire, usually cylindrical, in which a magnetic field is created by passing an electric current through it (see electromagnet). This field can be used to move an iron rod placed on its axis.
Mechanical valves attached to the rod can be operated by switching the current on or off, so converting electrical energy into mechanical energy. Solenoids are used to relay energy from the battery of an automobile to the starter motor by means of the ignition switch.
Tubular coil of wire producing magnetic field.
(griech.)Eisen- oder Stahlkörper, der andere anzieht. Die Kraftwirkung des M. geht von den beiden Polen aus, die bewirken, daß ein lose aufgehängter M. sich in N-S-Richtung ausrichtet (Kompaß-Prinzip); daher Bez. des nach N weisenden Pols als positiver oder Nordpol und entspr. des anderen als negativer oder Südpol. Gleiche Pole stoßen sich ab, ungleiche ziehen sich an. Man unterscheidet nach der Form Stab- und Hufeisen-M.
1. Magnetite that has polarity; SYN. loadstone.
2. Magnetite that possess polarity and has the power to attract as well as to be attracted magnetically; SYN. loadstone.
ETYM Old Eng. magnete, Old Fren. magnete, Latin magnes, -etis, Greek Magnetis lithos a magnet, metal that looked like silver, prop., Magnesian stone, from Greek Magnesia, a country in Thessaly. Related to Magnesia, Manganese.
Any object that forms a magnetic field (displays magnetism), either permanently or temporarily through induction, causing it to attract materials such as iron, cobalt, nickel, and alloys of these. It always has two magnetic poles, called north and south.
A device that attracts iron and produces a magnetic field.
