Elektromagnet
Sign in to saveMagnet, dessen Magnetfeld durch makroskopische elektrische Ströme erzeugt wird.
An electromagnet is a coil of wire wrapped around an iron core that produces a magnetic field when electric current flows through it. The strength of this magnetic field depends on how much current runs through the wire, making electromagnets useful devices whose magnetic power can be controlled by adjusting the electrical input.

Ein Elektromagnet besteht aus einer Spule, in der sich infolge eines elektrischen Stromes ein magnetisches Feld bildet. In der Spule befindet sich meist ein offener Eisenkern, der das Magnetfeld führt und verstärkt. Die Erfindung des Elektromagneten gelang dem Engländer William Sturgeon im Jahre 1826. Erstmals nachgewiesen wurde die elektromagnetische Wirkung 1820 von dem dänischen Physiker Hans Christian Ørsted.
